cmd/go: clean up x.exe properly in TestImportMain

More generally I'm concerned about these tests using
$GOROOT/src/cmd/go as scratch space, especially
combined wtih tg.parallel() - it's easy to believe some other
test might inadvertently also try to write x.exe about the
same time. This CL only solves the "didn't clean up x.exe"
problem and leaves for another day the "probably shouldn't
write to cmd/go at all" problem.

Fixes #22266.
