autotest: find the latest FW release across branches

A board might have more than one branch, and those branches
has different subdirectory styles.
Old style has a file, ${board}_firmware_from_source.tar.bz2, and
new style has a file, ${board}/firmware_from_source.tar.bz2.

This patch revises the get_the_latest_release_version() function
so that it can navigate each branch looking for new-styled release.

BUG=b:148287677
TEST=ran provision_FirmwareUpdate.ccd on atlas.
