getlocalename_l: fix _reent for _REENT_SMALL targets

The new _MB_CAPABALE-only _misc_reent member getlocalename_l_buf was
incorrectly initialized in the _REENT_INIT_MISC macro, so the build
failed for _REENT_SMALL targets, independet of the _MB_CAPABALE setting.

Fixes: 71511d4ac868 ("getlocalename_l: implement per SUS Base Specifications Issue 8 draft")
