kern: mac: pull mac_label_copyin_string out

A future commit to the area will further our jail integration and add
a use for this: the struct mac itself was already copied in as part of
vfs_buildopts(), so we only need to copyin the strings.

We add an explicit flag argument because the jail operation will need to
do it while holding the prison lock.
