vtysh: work around gcc bug #69981
The memtypes changes break gcc -O0 build (none of the other optimisation
levels are affected, *any* of -Og, -Os, -O1, etc. make this go away).
Unfortunately, the option supposed to control this doesn't actually work
(-fno-keep-static-const; that not working is the actual gcc bug).
The workaround is to avoid DECLARE_MTYPE statements when their paired
DEFINE_MTYPE isn't linked in. Thankfully, that's only a problem in a
single place in vtysh where bgp_memory.h gets chain-included.
(vtysh.c -> bgp_vty.h -> bgpd.h -> bgp_memory.h)
So, this just breaks the chain at bgp_vty.h.
No other compiler (clang & icc tested) has exhibited this problem.
