fuse2fs: compact all the boolean flags in struct fuse2fs

Compact all the booleans into u8 fields.  I'd go further and turn them
into bitfields but that breaks the fuse argument parsing macros, which
compute the offset of the structure fields, and gcc won't let us do that
to bit fields.  Still, 136 -> 112 bytes isn't bad.
