runtime(filetype): Modula-2 files with priority not detected (vim/vim#14055)
Problem: Modula-2 files with a specified priority are not detected.
Solution: Match the priority syntax in module header lines when
performing heuristic content detection.
Disable the :defcompile debug line. This was accidentally left enabled
in commit 68a8947.
