path/filepath: avoid assuming that GOROOT/test is present

GOROOT/test is pruned out by cmd/distpack. It isn't really needed for
the test anyway; the test can instead use the "src/unicode" subdirectory,
which is even within the same module.

This test was previously adjusted in CL 13467045 and CL 31859.

Unlike in previous iterations of the test, the directories used in
this revision are covered by the Go 1 compatibility policy and thus
unlikely to disappear.

For #24904.
