[OE-core] [PATCH V5] rootfs.py: allow removal of unneeded packages

[Stephano Cetola]

Current functionality allows for the removal of certain packages
based on the read-only image feature. This patch extends this
functionality by adding the FORCE_RO_REMOVE variable, which will
remove these packages regardless of any image features.
