remove unused BOARD_USES_COMBINED_RECOVERY

Change-Id: I79520c510488d63d469b0d1a3a099420f7de1fe6
Remove the line that deletes *.rc from the recovery ramdisk.
This is no longer necessary since recovery init.rc only includes "import /init.recovery.${ro.hardware}.rc".

Fix up the unpackbootimg target.

envsetup: Add pstest

  An easy way to cherry pick patch submissions from AOKP's
  gerrit instance. Nice for at a glance tests, or when
  using a mobile device to ssh into a buildbox.
  (copying patches via the Android browswer is painful.)

  Patch Set 2: fix bad formatting.
