vendor/rsc.io/pdf: import rsc.io/pdf library
This will be needed by some of the arch subdirs.
It obviously shouldn't be exposed for import,
so it must be vendor or internal.
Using vendor here is a bit of an experiment in how we might
use vendor in our own subrepos. Since the subrepo is new it
seems a reasonable test case.
