cmd/go: revert TestScript/build_trimpath to use ioutil.ReadFile

This call was changed to os.ReadFile in CL 266365, but the test also
builds that source file using gccgo if present, and released versions
of gccgo do not yet support ioutil.ReadFile.

Manually tested with gccgo gccgo 10.2.1 (see #35786).

Fixes #43974.
Updates #42026.
