Remove gdb.base/annota2.exp

[Jim Kingdon]

Some time ago, gdb.base/annota2.exp got copied to gdb.c++/annota2.exp.
However (due to oversight?), gdb.base/annota2.exp didn't get deleted
and in the meantime various bugfixes have been applied to
gdb.c++/annota2.exp and not gdb.base/annota2.exp.  Here's a suggested
ChangeLog entry for doing it now (I'm not submitting a diff, as there
are no changes other than deleting the file).

Perhaps this is an artifact of the way that GDB is moved over to
cvs.sourceware.com?  If so, the fix might be different...

	* gdb.base/annota2.exp: Removed; gdb.c++/annota2.exp has all
	the good bits from gdb.base/annota2.exp.
