bsd.prog.mk: Avoid redefining $PROG target

In rare cases, the PROG target is intentionally redefined before
including bsd.prog.mk, but when that happens a target redefinition
warning is emitting.  This adds a check for a pre-existing $PROG
target before attempting to define it.

It stops warnings from being emitted when loader and loader_tftp
are built.
