tests/functional: add 'archive_extract' to QemuBaseTest

Browse source 
This helper wrappers archive.archive_extract, forcing the use of the
scratch directory, to ensure any extracted files are cleaned at test
termination. If a specific member is requested, then the path to the
extracted file is also returned.
