cmd/go/internal/load: treat packages with errors as potentially main packages
If a package declares 'package main' but for some reason we fail to
read its name (for example, due to a permission or checksum error),
we may be tempted to drop the package from the output of
mainPackagesOnly. However, that leads to a confusing
"no packages loaded from …" error message.
Instead, we will treat packages with errors as potentially-main
packages, and print the error. At least if we print why the package is
broken, the user will understand that the weird behavior is due to the
broken package rather than, say, a typo on their part in the command
arguments.
Updates #42088
For #36460
