mk/relpath: Fix quoting

Previously there were two instances in this script which lacked proper
quoting. This resulted in `relpath` invocations in the binary
distribution Makefile producing incorrect results on Windows, leading to
confusing failures from `sed` and the production of empty package
registrations.

Fixes #24538.
