Makefile: remove DOCKER_BUILD_GOGC

Browse Source 
This option was added in 9672afa339 in 2016,
at which time tweaking GOGC showed a significant difference when building
the binary (`1m14.221s` vs `0m49.929s`).

Testing this Today doesn't show a real difference;

With GOGC=1000:

    rm -rf bundles/
    time hack/make.sh binary
    real	0m15.303s
    user	0m26.285s
    sys	0m6.383s

    real	0m4.931s
    user	0m3.103s
    sys	0m1.670s

    real	0m5.693s
    user	0m3.827s
    sys	0m2.384s

Without GOGC set;

    real	0m5.012s
    user	0m3.689s
    sys	0m1.549s

    real	0m5.298s
    user	0m3.997s
    sys	0m1.695s

    real	0m4.899s
    user	0m3.579s
    sys	0m1.423s
