[PATCH v3 2/3] t/lib-httpd: add the strip_access_log() helper function

[SZEDER Gábor]

Four tests in three httpd-related test scripts check the contents of
Apache's 'access.log', and they all do so by running 'sed' with the
exact same script consisting of four s/// commands to strip
uninteresting log fields and to vertically align the requested URLs.

Extract this into a common helper function 'strip_access_log' in
'lib-httpd.sh', and use it in all of those tests.
