David Crawshaw 4e2ef7f7f9 cmd/go: add source file contents to plugin hash
It is common to have multiple plugins built from ephemeral
source files all with the same name:

	# generate main.go
	go build -buildmode=plugin -o=p1.so main.go
	# rm main.go, generate new main.go
	go build -buildmode=plugin -o=p2.so main.go
	...

These different plugins currently have the same build ID,
and hence the same package path. This means only one can be
loaded.

To remove this restriction, this commit adds the contents of the
main package source files to the plugin hash.

Fixes #19358
