kbuild: Extend kbuild/defconfig tags support to exuberant ctags
The following patch extends kbuild/defconfig tags support to exuberant
ctags. The previous support is only for emacs ctags/etags programs.
This patch also corrects the kconfig regex for the emacs invocation.
Previously it would miss some instances because it assumed /^config
instead of /^[ \t]*config
