[PATCH 1/2] common/config: make set_prog_path() accept one argument only

[Eric Biggers <ebiggers3@gmail.com>]

From: Eric Biggers <ebiggers@google.com>

All callers of set_prog_path() pass it only one argument, the program to
find on the $PATH.  Therefore, to simplify things remove the unused code
which allowed fallback paths to be specified in the remaining arguments.
