Improve bsd.progs.mk compatibility with bsd.prog.mk

1. Do not install FILES/SCRIPTS multiple times if PROGS is specified; this is
   already handled via bsd.prog.mk when it's called recursively (PR: 191055,
   191955).
2. Some variables, like BINDIR and PROGNAME, default to a value if unset
   whereas others get appended to, like CFLAGS. Add support for the former case
   (PR: 191056)
3. Make "checkdpadd" and "clean" available targets for recursive execution.
