When a port is restored after being marked as broken, its builder won't
be able to test the port unless the -force flag is passed to make.bash.

This change makes it possible to configure such builders as so:

	makeScriptArgs: []string{
		// TODO(go.dev/issue/nnn): Temporarily force build
		// until the port is no longer marked as broken.
		"-force",
	},

To see test results before the port is no longer marked as broken.

This change stops reusing the value of allScriptArgs for make.bash args.
That doesn't break anything since only the misc-compile builders have a
non-empty allScriptArgs set, and that value is needed for buildall.bash,
not for make.bash.

For golang/go#56679.

It's empty so far. The next CL adds linux/sparc64.

Also add -force flag to the bootstrap.bash script
so that it's possible to use it with broken ports.

For #56679.

The linux/sparc64 port is incomplete—it doesn't work, and it doesn't
have a builder. Now that dist supports broken ports, mark it as such.

The incomplete map was created to hide ports that aren't functional
from dist list output. Now that we have the broken port concept, it
seems largely redundant, so remove it for now.

For #56679.
Updates #28944.
