[PATCH v2 3/4] git-compat-util.h: add FLOSS headers for HPE NonStop

From: "Randall S. Becker" <rsbecker@xxxxxxxxxxxxx>

The HPE NonStop (a.k.a. __TANDEM) platform cannot build git without
using the FLOSS package supplied by HPE. The convenient location
for including the relevant headers is in this file.

The NSIG define is also not defined on __TANDEM, so we define it
here as 100 if it is not defined only for __TANDEM builds.
