[Piglit] [PATCH 2/3] tests: Use FE_UPWARD only if its defined in fenv.h

[Ross Burton]

From: Khem Raj <raj.khem at gmail.com>

On ARM, musl does not define FE_* when arch does not have
VFP, (which is right interpretation), therefore check if
it is defined before using it.

Fixes errors like:

tests/general/roundmode-pixelstore.c:82:19: error: 'FE_UPWARD' undeclared (first use in this function)
  ret = fesetround(FE_UPWARD);
                   ^~~~~~~~~
