bpf: simplify definition of BPF_FIB_LOOKUP related flags
Previously, the BPF_FIB_LOOKUP_{DIRECT,OUTPUT} flags in the BPF UAPI
were defined with the help of BIT macro. This had the following issues:
- In order to use any of the flags, a user was required to depend
on <linux/bits.h>.
- No other flag in bpf.h uses the macro, so it seems that an unwritten
convention is to use (1 << (nr)) to define BPF-related flags.
Fixes: 87f5fc7e48dd ("bpf: Provide helper to do forwarding lookups in kernel FIB table")
