fix musl build failures

Missing _PATH_HOSTS and some NETDB defines when musl is enabled.

These are work arounds for now while we figure out where the real fix should reside (musl, gcompact, sssd):

./sssd-2.5.1/src/providers/fail_over.c:1199:19: error: '_PATH_HOSTS' undeclared (first use in this function)
|  1199 |                   _PATH_HOSTS);
|       |                   ^~~~~~~~~~~

and 

i./sssd-2.5.1/src/sss_client/nss_ipnetworks.c:415:21: error: 'NETDB_INTERNAL' undeclared (first use in this function)
|   415 |         *h_errnop = NETDB_INTERNAL;
