linuxloader: Add get_musl_loader_arch function

get_musl_loader_arch returns the arch part of ldso for musl, this is
used in get_musl_loader() as well as independently usable, which is
needed for multilib support in musl. Musl stores all ldso in /lib
be it multilib or not, therefore do not use base_libdir instead directly
use /lib
