Refactor routine to find single log content pattern in TAP tests
The same routine to check if a specific pattern can be found in the
server logs was copied over four different test scripts. This refactors
the whole to use a single routine located in PostgreSQL::Test::Cluster,
named log_contains, to grab the contents of the server logs and check
for a specific pattern.
On HEAD, the code previously used assumed that slurp_file() could not
handle an undefined offset, setting it to zero, but slurp_file() does
do an extra fseek() before retrieving the log contents only if an offset
is defined. In two places, the test was retrieving the full log
contents with slurp_file() after calling substr() to apply an offset,
ignoring that slurp_file() would be able to handle that.
Backpatch all the way down to ease the introduction of new tests that
could rely on the new routine.
