builtin/apply: make parse_single_patch() return -1 on error
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_single_patch() should return a negative
integer instead of calling die().
Let's do that by using error() and let's adjust the related test
cases accordingly.
