gdb: prepare for Seastar's "smp: allow having multiple instances of the smp class"

Browse Source 
scylladb/seastar@e6463df8a0 ("smp: allow
having multiple instances of the smp class") changes the type of
seastar::smp::_qs from a unique_ptr to a regular pointer. Adjust for
that change, with a fallback to support older versions.

Closes #8784
