icp: emit .note.GNU-stack section for all ELF targets

Browse Source 
On FreeBSD, linking the zfs kernel module with binutils ld 2.44 shows
the following warning:

    ld: warning: aesni-gcm-avx2-vaes.o: missing .note.GNU-stack section
    implies executable stack
    ld: NOTE: This behaviour is deprecated and will be removed in a
    future version of the linker

Some of the `.S` files under `module/icp/asm-x86_64/modes` check whether
to emit the `.note.GNU-stack` section using:

    #if defined(__linux__) && defined(__ELF__)

We could add `&& defined(__FreeBSD__)` to the test, but since all other
`.S` files in the OpenZFS tree use:

    #ifdef __ELF__

it would seem more logical to use that instead. Any recent ELF platform
should support these note sections by now.
