Make the use of gold linker configurable

Browse source 
Currently, ld.gold is always used for linking if found on the
system. There are some cases however when one may want to opt out
from using it. This patch adds the boolean field `rustc-with-gold`
to the `[tools]` section of `.servobuild`, which if set false,
disables the use of ld.gold.
