kbuild: remove stale dependency between Documentation/ and headers_install
Commit 8e2faea877eb ("Make Documenation depend on headers_install")
dates back to 2014, which is before Sphinx was introduced for the
kernel documentation.
Since none of DOC_TARGET requires headers_install, it is strange to
run it only for the single target "Documentation/".
