Add path mtime (#9057)
This can be used to print the modification time, like `stat` with some
options.

The reason is that `stat` has caused us a number of portability
headaches:

1. It's not available everywhere by default
2. The versions are quite different

For instance, with GNU stat it's `stat -c '%Y'`, with macOS it's `stat
-f %m`.

So now checking a cache file can be done just with builtins.
