InnoDB, XtraDB: handle EOPNOTSUPP from posix_fallocate()
On some libc (like musl[1]), posix_fallocate() is a fallocate() syscall
wrapper, and does not include fallback code like glibc does. In that
case, EOPNOTSUPP is returned if underlying filesystem does not
support fallocate() with mode = 0.
This patch enables falling back to writing zeros when EOPNOTSUPP, fixes
some cases like running on filesystem without proper fallocate support
on Alpine.
