Florian Klink fd4c7c10a8 chore(3p/overlays/patches): vendor cbtemulator UDS patch
I updated https://github.com/googleapis/google-cloud-go/pull/9665 in the
meantime, and GH decided to GC the patches.

Vendor the patch in for now (manually stripping the `bigtable/` prefix
in the path). Hopefully the PR itself gets merged soon.

feat(bigtable/emulator): allow listening on Unix Domain Sockets
cbtemulator listening on unix domain sockets is much easier than trying
to allocate free TCP ports, especially if many cbtemulators are run at
the same time in integration tests.
This adds an additional flag, address, which has priority if it's set,
rather than host:port.
`NewServer` already takes a `laddr string`, so we simply check for it to
contain slashes, and if so, listen on unix, rather than TCP.

feat(bigtable): clean up unix socket on close
Call srv.Close when receiving an interrupt, and delete the unix domain
