[SSSD] [PATCH] Minor fixes

[Sumit Bose]

Hi,

0001: I got an error with older python version when just calling exit().
      'TypeError: 'str' object is not callable'

0002: make check failed when using the tar ball, because elapi_ut.conf
      was missing

0003: Older versions of check do not have test loops.

bye,
Sumit
