gdb: fix tab after space indentation issues

I spotted some indentation issues where we had some spaces followed by
tabs at beginning of line, that I wanted to fix.  So while at it, I did
a quick grep to find and fix all I could find.

gdb/ChangeLog:

	* Fix tab after space indentation issues throughout.
