git-compat-util.h: use apparently more common __sgi macro to detect SGI IRIX

IRIX 6.5.26m does not define the 'sgi' macro, but it does define an '__sgi'
macro.  Since later IRIX versions (6.5.29m) define both macros, and since
an underscore prefixed macro is preferred anyway, use '__sgi' to detect
compilation on SGI IRIX.
