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. (cherry picked from commit 99135114ba23c3110b7e4e650fabdc5e639746b7) (note: tests excluded as test-in-container infrastructure missing)
