[PATCH 3/4] t/lib-httpd: drop SSLMutex config

The SSL config enabled by setting LIB_HTTPD_SSL does not work with Apache versions greater than 2.2, as more recent versions complain about the SSLMutex directive. According to https://httpd.apache.org/docs/current/upgrading.html:

  Directives AcceptMutex, LockFile, RewriteLock, SSLMutex,
  SSLStaplingMutex, and WatchdogMutexPath have been replaced with a
  single Mutex directive. You will need to evaluate any use of these
  removed directives in your 2.2 configuration to determine if they can
  just be deleted or will need to be replaced using Mutex.

Deleting this line will just use the system default, which seems sensible. The original came as part of faa4bc35a0 (http-push: add regression tests, 2008-02-27), but no specific reason is given there (or on the mailing list) for its presence.

If we can't drop support for 2.2 in patch 2, then this would need to be
adjusted with an IfVersion.
