rm: allow -r flag to be specified multiple times

Browse source 
GNU rm allows the `-r` flag to be specified multiple times, but
uutils/coreutils would previously exit with an error.

I encountered this while attempting to run `make clean` on the
Postgres source tree (github.com/postgres/postgres).

Updates #1663.
