cmd/internal/moddeps: don't skip directories if there are unusual files 

Previously, if there was a non-directory file with the name vendor or
testdata in the Go source tree, it was possible for some directories
to be skipped by filepath.Walk performed in findGorootModules.

As unusual and unlikely as such non-directory files are, it's better
to ensure all directories are visited, and all modules in the GOROOT
source tree are found.

This increases confidence that tests relying on findGorootModule
will not have unexpected false negatives.

For #36851.
For #36907.
