6a2e26b80c feat(archroot): add support for systemd-nspawn args
Allow passing additional command line args to systemd-nspawn for
makechrootpkg builds. The use case is to allow various test suites to
benefit from greater coverage by selectively allowing syscalls and/or
capabilities that would otherwise be blocked by the standard
systemd-nspawn container.

Example usage:

makechrootpkg -s --machine=foo,--keep-unit,--system-call-filter="munlockall @keyring"
