scripts/buildstats-diff: Add option to filter tasks

Browse Source 
Adds a command line option to filter out the buildstats-diff report by
one more more tasks. e.g.:

 buildstats-diff --only-task do_compile A B

will only show the differences for do_compile tasks. The --only-task
option can be specified multiple times to filter out multiple tasks at
once.
