endiantest: Fix #if expression
Without this, `gcc -E endiantest.c` can fail and return the incorrect
endiannes as well as exiting with non-zero. Here is the actual error
shown in the output:
endiantest.c:2:31: error: #if with no expression
#if __FLASHROM_LITTLE_ENDIAN__
I was able to reproduce this using gcc-6.3.0 and clang-4.0.1, but
newer compilers didn't have this issue.
