tools/perf: Add --exclude-buildids option to perf archive command 



When make a perf archive, it may contains the binaries that user did not want to ship with,
add --exclude-buildids option to specify a file which contains the buildids need to be
excluded. The file can be generated from command:

    perf buildid-list -i perf.data --with-hits | grep -v "^ " > exclude-buildids.txt

Then remove the lines from the exclude-buildids.txt for buildids should be included.

# buildids file, you can use the following command:

# 	perf buildid-list -i perf.data --with-hits | grep -v "^ " > exclude_buildids.txt

# You can edit the file to remove the lines that you want to keep in the archive, then:
