Remove 'grp' and merge into 'nss' and 'posix'
The majority of grp routines are entry points for nss functionality. This commit removes the 'grp' subdirectory and moves all nss-relevant functionality and all tests to 'nss', and the 'setgroups' stub into 'posix' (alongside the 'getgroups' stub). References to grp/ are accordingly changed. In addition, compat-initgroups.c, a fallback implementation of initgroups is renamed to initgroups-fallback.c so that the build system does not confuse it for nss_compat/compat-initgroups.c. Build time improves very slightly; e.g. down from an average of 45.5s to 44.5s on an 8-thread mobile x86_64 CPU. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
