[PATCH] bitbake.conf/utils: Drop some OVERRIDES from FILESPATH

[Richard Purdie <richard.purdie@linuxfoundation.org>]

There are several overrides that don't make sense as part of FILESPATH. This
introduces FILESOVERRIDES and allows us to drop some of the pointless ones,
simplifying the files search path further and improving the user experience.

If needed by specific recipes, other overrides can be added back in for
specific cases.
