Fix linking with libpayload

o Move flashbuses_to_text() to flashrom.c, it's not a cli function.
o Guard `!defined(HAVE_STRNLEN)`. This guard was introduced in
  23e10b87 (Add a bunch of new/tested stuff and various small
  changes 24) to support older BSDs. It's probably completely
  broken because HAVE_STRNLEN is presumably a GNU autotools
  thing. But we can't fix it without retesting these older BSDs.
