Vendor filepath inside template-haskell
Adding filepath as a dependency of template-haskell means that it can't
be reinstalled if any build-plan depends on template-haskell.
This is a temporary solution for the 9.4 release.
A longer term solution is to split-up the template-haskell package into
the wired-in part and a non-wired-in part which can be reinstalled. This
was deemed quite risky on the 9.4 release timescale.
Fixes #21738
