[PATCH] scripts/tags.sh: Include tools directory in tags generation

[Vipin Sharma <vipinsh@google.com>]

Add tools directory in generating tags and quiet the "No such file or
directory" warnings.

It reverts the changes introduced in commit 162343a876f1
("scripts/tags.sh: exclude tools directory from tags generation") while
maintainig the original intent of the patch to get rid of the warnings.
This allows the root level cscope files to include tools source code
besides kernel and a single place to browse the code for both.

I have found myself many times to browse tools and other part of the
kernel code together. Excluding tools from the root level cscope makes
it difficult to efficiently move between files and find user api
definitions.

Root cause of these warning is due to generated .cmd files which use
relative paths in some files, I am not sure how to make them absolute
file paths which can satisfy realpath warnings. Also, not sure if those
warnings are helpful and should be kept. Passing "-q" to realpath seems
easier solution. Please, let me know if there is a better alternative.

Thanks
