nss-myhostname: Stop trying to build for musl

There's no point in building an NSS module for a C library
that doesn't support NSS.

-Subject: [PATCH] nss-myhostname: Check for nss.h presense before use
-
-We do not have nss.h on musl e.g. and configury is already checking for
-nss.h presence, use this to define needed data structures if nss.h is
-missing on a given libc implementation on a platform
-
-include stdint.h for uint32_h definition
