Change how errno values are printed, for portability
Reported and suggested by Pino Toscano: The Hurd does not #define the EFOO constants as simple integers, but as expressions. This made the code that generates errnos.h to misinterpret the value, and always print 0 for every error code. We fix this by instead using the EFOO macro in errnos.h, so that the preprocessor evaluates it correctly. This is the right thing to do anyway, for every platform. Thus the table changes from {"EFOO",42} to {"EFOO",EFOO} for each entry.
