unix: implement InotifyInit using InotifyInit1 on all linux platforms

Most newer architectures (e.g. arm64 or riscv64) don't provide the
inotify_init syscall and some systems (e.g. Android) block it even if it
were available. Internally, the inotify_init syscall is implemented
exactly like inotify_init1 [1], so there is no point in having a
separate wrapper on some platforms.
