[PATCH] PR libstdc++/67440 make pretty printers work with GDB 7.6 again

[Jonathan Wakely]

The gdb.Type.name attribute was only added in GDB 7.7, so several
printer tests fail on older GDB versions. Since all we need is to
strip cv-qualifiers we can use gdb.Type.unqualified() for that.

	PR libstdc++/67440
	* python/libstdcxx/v6/printers.py (find_type): Avoid gdb.Type.name
	for GDB 7.6 compatibility, use gdb.Type.unqualified instead.

Tested powerpc64le-linux (CentOS 7.3) and committed to trunk.
