bitbake: bitbake-config-build: add an alias to bitbake-layers

This alias is intended for managing specific local configs and it
is prompted by adding support for config fragments (in a separate
commit to oe-core); after some deliberation I concluded there should be
a separate tool, as bitbake-layers is already somewhat over-stuffed,
and this will give space for more build/conf/* operations in the future
that anyone can come up with (such as tweaking site-specific items
in site.conf etc.)

The alias completely reuses existing code via symlink and
the difference is in where it looks for plugins.
