src.opts.mk: Retire BSD_CPIO option

Prior to commit 6973701a00 ("1. Make the BSD version of cpio the
default [1]") GNU cpio was installed unconditionally.  The BSD_CPIO
option was added when we introduced the BSD licensed, libarchive-based
cpio, to support installation of GNU cpio, libarchive cpio, or both.

GNU cpio was removed long ago and there is no longer a need for this
option.  We can just install BSD cpio unconditionally.
