Masahiro Yamada f8f4dc7685 scripts/jobserver-exec: parse the last --jobserver-auth= option ...

In the GNU Make manual, the section "Sharing Job Slots with GNU make"
says:

    Be aware that the MAKEFLAGS variable may contain multiple instances
    of the --jobserver-auth= option. Only the last instance is relevant.

Take the last element of the array, not the first.
