Makefile.common: Remove redundant conditionals.

C89 builds are only used for the qb build system currently and these are
already checked in qb/config.params.sh.

Additionally the HAVE_NETWORKING check is handled with qb/config.lib.sh
where HAVE_SSL and HAVE_BUILTINMBEDTLS are disabled if networking is
also disabled. The other build systems should never define HAVE_SSL or
HAVE_BUILTINMBEDTLS without HAVE_NETWORKING. Also there are no other
build systems that rely on Makefile.common using this yet.
