Update shada.c to use libuv error constants instead of errno constants

Browse Source 
From #3473, shada.c used errno constants (e.g. ENOENT) to check the return
of os_open(), but in Windows the return from libuv functions is not -errno.
Instead use libuv error constants (e.g UV_ENOENT) for error checks.
