scripts/bitbake: Update to help rebuild pseudo-native

Attempt to detect when pseudo-native has been updated.  If it has been updated,
or if the user is attempting an operation with pseudo-native in the name, force
a build of pseudo-native, prior to running the main build.

Note: This causes a build, then clean in the case of
   bitbake -c cleansstate pseudo-native
