tools: rename to 'utils'

After some discussion, we found out that "tools" has the four first
letters identical to the "toolchain" subfolder, which makes it a bit
unpractical with tab-completion. So, this commit renames "tools" to
"utils", which is more tab-completion-friendly.

This has been discussed with Arnout and Yann.

 Usage examples:
 - to get a list of check functions that would be called without actually
   calling them you can use the --dry-run option:
-$ tools/check-package --dry-run package/yourfavorite/*
+$ utils/check-package --dry-run package/yourfavorite/*
 
 - when you just added a new check function, e.g. Something, check how it behaves
   for all current packages:
-$ tools/check-package --include-only Something $(find package -type f)
+$ utils/check-package --include-only Something $(find package -type f)
 
 - the effective processing time (when the .pyc were already generated and all
   files to be processed are cached in the RAM) should stay in the order of few
   seconds:
-$ tools/check-package $(find package -type f) >/dev/null ; \
