SystemTools: Fix Touch to avoid requiring file ownership
SystemTools::Touch should only require +w file permissions. The previous implementation used `stat` to get the current time, and then passed that time to one of utimensat/utimes/utime. However, utimes/utimensat only permit an arbitrary-time argument to be passed by the file owner. Therefore, per the docs, we pass NULL for the `times` argument to utimes and utimensat, to indicate using the current time. This is permitted for any UID with +w on the file. Remove plain `utime` fallback that is no longer necessary.
