This patch enables the usage of the '@' character in variable flag names. One use case of variable flags is to indicate and set the namespace of some systemd services/targets. The filenames of systemd services/targets might contain the '@' character if they are template unit files that can take in a single parameter/argument and be instanced multiple times, as indicated by systemd's official manual page. This patch is successfully verified by creating a custom BitBake recipe that sets and unsets the value of a variable flag with the '@' character in its name and ensuring that no ParseError is being thrown. A regression test has also been added to `bb.parse`. `bin/bitbake-selftest` has also been successfully executed and all tests passed.
