LOG: [libc] [math] Fix build bot failure introduced by unit test in PR #201154 (#203457)

The root cause is that the unit test
`libc/test/src/math/RoundToIntegerTest.h` `#include <cfenv>` which
requires the macro `__GLIBC_PREREQ` to be defined. But in that riscv32
runtime, seems like it's not defined.

Removing the include works fine, and at the same time, would resolve the
failure.

Added: 
    

Modified: 
    libc/test/src/math/RoundToIntegerTest.h

Removed:
