sdcard: Respect check_caller_access_to_name on readdir() calls

While looking at a blocked path failed as expected when trying
to access it with a stat(), read(), or getattr(), readdir() still
returned the entry, making devices with mounted external storage fail
com.android.cts.appsecurity.AppSecurityTests#testExternalStorageWrite
by trying to interact with otherwise invisible paths.

Fixit by skipping all entries that would've been made invisible at
LOOKUP

sdcard: Link to cutils and libc as DSOs

There's no reason to link this statically, especially since we're
building a shared binary anyway. Reduce binary size from 108k to 18k

Change CM recovery install script filename [2/2]

This is part 2/2 to maintain backwards compatibility with CWM's
verify_root_and_recovery() function. CWM checks if install-recovery.sh
exists and has an executable flag set, then offers to disable the script
for the user. CM now controls this with the persist.sys.recovery_update
property which is configurable via settings, so we don't need to
double-check this.

This changes the name of the recovery install script to
install-cm-recovery.sh.

healthd: increase healthd fast timer to 10mins instead of 1min

healthd 1 min wakeups are causing significant power impact
during static display use case. so increasing the timer to 10min.

healthd: Disable the RTC wakeup timer

The timer is used here to avoid battery drained to zero. But the periodic
wakeup during suspend should not be needed as MSM PMIC already support
that by trigger interrupt to avoid the critical low battery situation.
This will save more power. And if the design is not support HW interrupt
of low battery, need to enable the timer to periodic check.

healthd: Only use battery values that seems legit

On some devices, there are other sysfs paths having a "capacity"
node than just the battery, which can return a weirdo value. We
make sure we only use legit battery levels (> 0%).

rootdir: Allow to use a custom environ.rc
