Call getgrnam_r repeatedly if we receive ERANGE

Some large enterprises have huge groups that need to be resolved.

Example: I have a group that needs a 2MB buffer ;)

Title:
  rsyslogd please apply patch for large group handling

Status in Rsyslog:
  Confirmed

Bug description:

  rsyslog uses a static 2048 character buffer to perform group lookups.
  Some of us have large groups and need a larger buffer. This patch
  repeatedly calls getgrnam_r until it gets a buffer of sufficient size.
