templater: replace templatepath() with function that also opens the file
For frozen binaries, such as those created by PyOxidizer, I plan to
make it so the templatespec can keep an opened file/resource to read
from instead of needing a file path. Having `templatepath()` return an
opened file should help with that. At this point, it's just a wasteful
extra opening of mapfiles that we'll open again later. I'll update the
read-side next so it reads from the file-like object without opening
the file again.
