Fix compilation with missing inotify_init1

Commit c05c7a7306a23a4b01d1606172b142c45caffc92
breaks cross compilation for mips (and other
compilations without CONFIG_INOTIFY1):

make[1]: Entering directory `/qemu/bin/mips'

/qemu/linux-user/syscall.c: In function ‘do_syscall’:
/qemu/linux-user/syscall.c:7067: error: implicit declaration of function ‘sys_inotify_init1’
