nss_files: Use generic result pointer in parse_line
As a result, all parse_line functions have the same prototype, except
for that producing struct hostent.  This change is ABI-compatible, so
it does not alter the internal GLIBC_PRIVATE ABI (otherwise we should
probably have renamed the exported functions).

A future change will use this to implement a generict fget*ent_r
function.
