builtin/apply: make parse_chunk() return a negative integer on error
To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing or exit()ing.
To do that in a compatible manner with the rest of the error handling
in builtin/apply.c, parse_chunk() should return a negative integer
instead of calling die() or exit().
As parse_chunk() is called only by apply_patch() which already
returns either -1 or -128 when an error happened, let's make it also
return -1 or -128.
This makes it compatible with what find_header() and parse_binary()
already return.
