Switch to the new atomic Uint64.Add api
The new api guarantees that the value is aligned, preventing
stuff like this on 32 bit platforms:
goroutine 26 [running]:
internal/runtime/atomic.panicUnaligned()
/usr/lib/go-1.24/src/internal/runtime/atomic/unaligned.go:8 +0x24
internal/runtime/atomic.Xadd64(0x2496c74, 0x1)
/usr/lib/go-1.24/src/internal/runtime/atomic/atomic_arm.s:318 +0x14
github.com/rfjakob/gocryptfs/internal/inomap.(*InoMap).NextSpillIno(0x2496c60)
Fixes https://github.com/rfjakob/gocryptfs/issues/912
