Make TWRP compile for arm64

-Remove dosfstools for arm64 until we can make it compile
-Fix TW_USE_TOOLBOX flag to work again
-Fix symlinking and handling of sh when using mksh
-Fix legacy properties to find futex_wake function
-Fix libcrecovery to not use bsd_signal anymore
-Fix rules for building with regards to libcrecovery
-Update toolbox_recovery rules to compile tools in lollipop
-Fix a few compile errors specific to arm64

Testers report that TWRP does not boot on Nexus 9 and we fail to
get a shell for adb shell. At least it compiles without errors.

Add lollipop decrypt support

Kang in cryptfs.c and cryptfs.h from vold.
Use TW_INCLUDE_L_CRYPTO := true to enable.
Ramdisk must contain the normal fstab file in the root in the
usual format of:
fstab.{ro.hardware}
For examble for Nexus 5:
fstab.hammerhead
Or on many Qualcomm devices:
fstab.qcom

Tested against Android 5.0 lollipop on Nexus 7 2012 grouper. Not
sure if or how this will work when we are dealing with a device
with a hardware keystore. Long term we need to add a GUI element
to allow entering a pattern. For now you can decrypt a pattern
unlock by converting the dots to numbers in the following format:
123
456
789

So an upper-case L would translate to 14789 as a password entered
on the keyboard.

Tweak 5.0 L decrypt

Mount the vendor partition if it exists so we can use any
proprietary files we may need.
Relocate auto decrypt when default_password is in use to after all
partitions are added so that we can mount the vendor partition.

Add flag for including additional files built from source in TWRP

Some devices may need additional binaries or libs that TWRP
normally does not need included in /sbin
Use TW_RECOVERY_ADDITIONAL_RELINK_FILES to build them from source
and get them added to the recovery ramdisk.
For example, Nexus 9 needs libc++ included in order to decrypt
the data partition. The following will build it from source and
include it in TWRP:
TARGET_RECOVERY_DEVICE_MODULES := libc++
TW_RECOVERY_ADDITIONAL_RELINK_FILES := \
    out/target/product/volantis/system/lib/libc++.so

Add /firmware to the mount list for L decrypt

Needed by Nexus 6 and possibly others

Fix process to disable stock recovery flashing

/system/etc/install-recovery.sh no longer exists on AOSP devices
so we will stop checking for it.

Properly set tw_settings_path after decrypt on data media devices

When tw_settings_path is not set correctly for /data/media/0 when
present, custom themes will not load (and who knows what else may
also be broken) so set it properly after decrypting the device.
