base-linux: omit unused lib/mk/ from API recipe

Browse Source 
The 'base-linux' API is used by hybrid Genode/Linux programs for the
lx_hybrid library. This API archive happend to contain other libraries -
like seccomp - that are solely needed for building core. With the change
of the build system in issue #4599, the build system would attempt to
build all libraries instead of merely the library dependencies of the
available targets. Hence, it would trigger the build of, e.g.,  the
seccomp library for each user of the base-linux API.

This patch avoids these superfluous build steps by pruning the content
of lib/mk/ to the libraries actually needed for lx_hybrid users.
