bootstrap: make 'test rustdoc' an alias for running all rustdoc tests

[lolbinarycat]

now that tests/rustdoc has been renamed, we can do this.

note this is not the set of tests that can fail when rustdoc is modifed (an obvious example is tidy, a less obvious example is the rustdoc run-make tests), it is the set of tests suites that are rustdoc-specific, which seems the most intuitive.

cc @GuillaumeGomez for t-rustdoc approval
