[PATCH 07/17] lxc_fuse: Prefer O_ACCMODE instead of & 3

[Michal Privoznik]

In lxcProcOpen() we want to check whether the /proc/memfile is
being opened only for read. For that we check the fi->flags which
correspond to flags open() call. Instead of explicitly masking
the last two bits use O_ACCMODE constant, which is deemed to be
more portable.
