insane: add checking to standardize how .bbappend files do FILESEXTRAPATHS

When adding patches or config files from bbappend files, it requires
the use of FILESEXTRAPATHS, which has been an issue and failure point
for people starting to work with bitbake and oe-core.

We add checking to standardize how to use FILESEXTRAPATHS. Only the
format of:
  FILESEXTRAPATHS_append := ":${THISDIR}/Your_Files_Path" or
  FILESEXTRAPATHS_prepend := "${THISDIR}/Your_Files_Path:"
is acceptable.
