nss_db: fix endent wrt NULL mappings [BZ #24695] [BZ #24696]
nss_db allows for getpwent et al to be called without a set*ent,
but it only works once. After the last get*ent a set*ent is
required to restart, because the end*ent did not properly reset
the module. Resetting it to NULL allows for a proper restart.
If the database doesn't exist, however, end*ent erroniously called
munmap which set errno.
The test case runs "makedb" inside the testroot, so needs selinux
DSOs installed.
