Add option for link concurrency.
Skia's buildbots, particularly Windows builds with LTO, are held back by the
link pool. We'd like to play around with this number a bit. Any problem
checking an environment variable first before doing the RAM-based calculation?
Testing: ran with and without GYP_LINK_CONCURRENCY=90, looked at build.ninja
