The message buffer of DumpException doesn't account for additional
strings such as strerror(), device nodes, or filenames. Make it a bit
larger to be safe.
This fixes the following GCC8 compile warnings:
In file included from vm_dump.h:62,
from vm_dump.cpp:17:
dump.h: In static member function ‘static Dump::DumpType
VMDump::getDumpType(const char*)’:
