builtin/apply: make parse_traditional_patch() return -1 on error

Browse source 
To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.

To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", parse_traditional_patch() should return -1
instead of calling die().
