dump-guest-memory: more descriptive lookup_type failure
We've seen a few reports of
(gdb) source /usr/share/qemu-kvm/dump-guest-memory.py
Traceback (most recent call last):
File "/usr/share/qemu-kvm/dump-guest-memory.py", line 19, in <module>
UINTPTR_T = gdb.lookup_type("uintptr_t")
gdb.error: No type named uintptr_t.
This occurs when symbols haven't been loaded first, i.e. neither a
QEMU binary was loaded nor a QEMU process was attached first. Let's
better inform the user of how to fix the issue themselves in order
to avoid more reports.
