kbuild: fake the "Entering directory ..." message more simply

Browse Source 
Commit c2e28dc975
(kbuild: Print the name of the build directory)
added a gimmick to show the "Entering directory ...".

Instead of echoing the hard-coded message (that is, we need to know
the exact message), moving --no-print-directory would be easier.
