am: simplify parsing of "--[no-]keep-cr"

Browse source 
Command line options "--keep-cr" and its negation trigger
OPT_SET_INT_F(PARSE_OPT_NONEG) to set a variable to 1 and 0
respectively.  Using OPT_SET_INT() to implement the positive variant
that sets the variable to 1 without specifying PARSE_OPT_NONEG gives
us the negative variant to set it to 0 for free.
