package/mysql: do not force a static build for internal programs

mysql wants to statically link some of the programs it uses internally,
like conf_to_src (whatever it is used for) which links against -lz.

This does not work for a shared-only build, as we would be missing
libz.a in that case.

Fix that by not forcing static builds for internal programs.

Fixes a slew of autobuild failures:

+Otherwise, it tries to link against a static libz, which may not exist
