Update makefiles to no longer rely on INTERNAL_RECOVERY_FILES. Define
LOCAL_ADDITIONAL_DEPENDENCIES instead.
Set LOCAL_LDFLAGS to properly link recovery executable.

Enable TWRP to reside alongside other recoveries with the naming
convention: bootable/recovery(-flag). If TWRP resides at
bootable/recovery and a device does not specify RECOVERY_VARIANT, then
it will build like normal. If TWRP resides at bootable/recovery-twrp,
then its makefiles will only be parsed if a device specifies
'RECOVERY_VARIANT := twrp'. This prevents TWRP specific makefile
warnings/errors (notably, missing DEVICE_RESOLUTION) when another
recovery is being built.
