chore(rust): add opt_get! and expose some FMODE_* as Rust const
In an effort to rewrite `bch2_read_super` from C to Rust,
it is neccessary to have `opt_get!` macro defined, and some
FMODE_* consts (defined as macro in `include/linux/blkdev.h`)
defined as Rust const.
Bindgen is currently unable to exapnd C functional macro [1],
this this commit use the workaround as introduced in [2].
