383 Fixed masks for major and minor in fuse-lite for OpenIndiana

Browse Source 
On Solaris/OpenIndiana, the major and minor fields in st_rdev have to
be represented on 14 bits and 18 bits respectively. They must have
the same representation on 32-bit and 64-bit builds as the kernel
and the library do not know the word size of each other.
