tools: e2fsprogs: drop the e4defrag patch

Considering that this patch to not build e4defrag was added 12 years ago
because:
Compilation fails on older systems due to missing syscalls

I think its safe to say that enough time is passed so that whatever those
older systems were are either updated or not used anymore so lets drop
the patch.
