Drop gdb versionning.

Cherry picked and adapted from commit 0efc808f from the original author
of kdbg, code available at https://github.com/j6t/kdbg under GPL 2.0"

Quote from the author:
In early days of KDbg, it was important to use a suitable command to load
a core file. This was before gdb 4.16. To pick the right command, the
version number was parsed from gdb's greeting.

At least with modern gdb the regular expression does not match anymore.
So let's assume that nobody is using ancient gdb anymore, and always use
the modern command.
