Add support for -v option on OpenBSD

The `-v` (verbose) flag for `cp`, `ln`, and `rm` is not standard. It is
simple to implement using shell functions, so introduce `cp_v`, `ln_v`,
and `rm_v`. These shell functions use the existing `$VERBOSE` variable
for printing, which simplifies the code and reduces the number of
variables.

Fixes #61.
