Make UTIL_countPhysicalCores() work under Cygwin (#1941)

Browse Source 
Cygwin currently uses the fallback implementation which just returns 1 every time,
which leads to bad performance when zstd is called with -T0 for example.

Instead use the POSIX implementation used for the BSDs which works just fine under Cygwin.

Tested under Cygwin and MSYS2.
