[PATCH] wineinstall - Add support for parallel builds using 'nproc' to detect cpu count

[Chris Morgan]

Parallel builds can greatly reduce the overall build time on modern multi-core processors.

Fall back to two parallel builds in the case where nproc is unavailable, most modern
processors have at least two cores.
