fuse/blackmatch: fix platform specific problems in repr_flags

the repr_flags debug/logging function had a list of fields from the os
module that might be passed into an open() call, but it included at
least one which was available on the mac but not on linux. symmetrically
linux has numerous flags which are not present on the mac. the repr_flags
function is now tolerant of flags not being present, and has an expanded
list of flags
