Fix missing genrule srcs and tools with ALLOW_MISSING_DEPENDENCIES=true

Set the location label for missing srcs and tools to avoid
nonsensical errors when parsing the command.

Cherry-pick note: Being cherry-picked to qt-dev to fix unbundled -qt
builds, see b/130588113.
Bug: 130588113

Test: genrule_test.go
