internal/coverage: fix bug in text-format coverage output with multiple packages
In ProcessCoverTestDir pass the selected set of packages to
EmitTextual in addition to EmitPercent, so that when we have runs with
multiple packages selected but without -coverpkg, text format output
for package P was incorrectly including output for P's covered
dependencies. This is in effect an extension of the fix for issue
65570.
Includes a cmd/go script test to verify correct behavior; ideally it
would be nice to locate this test in .../internal/coverage somewhere
but at the moment script tests are only supported for
cmd/{go,compile,link}.
Updates #65570.
Fixes #70244.
