package/multimedia: apply libtool patch where possible

Now that we have libtool-2.2.x patch support, we can get rid of a bunch
of _LIBTOOL_PATH = NO, fixing (potential) cross link issues.

Notice: libmad/libid3tag/madplay/taglib not changed, as they use a very
old 1.5 version, where our buildroot-libtool-v1.5.patch doesn't apply.
