genksyms: Handle typeof_unqual keyword and __seg_{fs,gs} qualifiers

Browse Source 
Handle typeof_unqual, __typeof_unqual and __typeof_unqual__ keywords
using TYPEOF_KEYW token in the same way as typeof keyword.

Also ignore x86 __seg_fs and __seg_gs named address space qualifiers
using X86_SEG_KEYW token in the same way as const, volatile or
restrict qualifiers.

Fixes: ac053946f5c4 ("compiler.h: introduce TYPEOF_UNQUAL() macro")
