Deactivate _FORTIFY_SOURCE in jitterentropy-base.c
This fixes compilation with glibc.
_FORTIFY_SOURCE only works with compiler optimizations activated.
We have to deactivate it when we set -O0.
This fixes the following error message with glibc:
error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
musl libc does not show an error message in this case, but has the same
internal problems.
