[PATCH 03/12] oe-build-perf-test: rename log file and implement --log-file

[Markus Lehtonen <markus.lehtonen@linux.intel.com>]

Rename the (main) log file of the oe-build-perf-test script from
'output.log' to 'oe-build-perf-test.log'. Also, add a new command line
option --log-file which makes it possible to use an alternative log file
name/path, if needed.  Note that the file name/path is relative to the
output directory.
