Workaround for old gnu tar, failing to restore timestamps on symlinks.

Older versions of GNU tar fail to set the timestamps on symlinks, which makes
them appear too recent/new to be backed up immediately, causing
test_bbackupd_uploads_files() for example to fail. Fixed by restoring the
timestamps manually after extracting the fixture archive.

This resulted in symlinks in fixture test files
