kbuild: Extend kbuild/defconfig tags support to exuberant ctags

Browse Source 
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
