ota: Let devices specify their own recovery-from-boot.p installer

Some devices apply transformations to the installed images, making
the sha1 checksums fail (or, worse, generating invalid images). If
"/system/etc/recovery-transform.sh" exists, run that instead, passing
the expected sizes and checksums as arguments in the form of

recovery-transform.sh <recovery_size> <recovery_sha1> <boot_size> <boot_sha1>

A direct emulation of the standard patcher could look like this, transformations
should be added as needed.

----------------
RECSIZE=$1
RECSHA1=$2
BOOTSIZE=$3
BOOTSHA1=$4

dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=$C/recovery.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=$C/boot.img

if ! applypatch -c EMMC:$C/recovery.img:$RECSIZE:$RECSHA1; then
  log -t recovery "Installing new recovery image"
  applypatch -b /system/etc/recovery-resource.dat EMMC:$C/boot.img:$BOOTSIZE:$BOOTSHA1 EMMC:$C/recovery.img $RECSHA1 $RECSIZE $BOOTSHA1:/system/recovery-from-boot.p || exit 1
else
  log -t recovery "Recovery image already installed"
fi

otasigcheck: Go back to the key-rewrite check.

Using an intermediate file had the at-the-time unintended but good
side-effect of making execution failures (absent script, no
busybox in recovery, bad selinux setup) pass gracefully. Since this
check is intended as a blacklist, blocking the update when only
sure that breakage will ensue, that was a nice thing to get.

Checking the return code, while cleaner, is making non-key-related
failures like those mentioned above abort execution of the script.
The key itself isn't even checked, yet we're aborting because of it.

So go back to the original behavior: In case we're not sure... pass.

To do:
This can be cleaned up differently, and to the same effect, by returning
an explicit error code from the script and aborting when that error
comes up. Change the script to do that and come back here. :)

Revert "otasigcheck: Go back to the key-rewrite check."

sigcheck now returns an explicit abort code
