[OS-BUILD PATCHv3 7/19] spec: Fix separate tools build

spec: Fix separate tools build

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2054579
Upstream Status: RHEL only

If we re building only tools without kernel, we need to generate config
headers and prepare tree for modules building. The modules_prepare target
will cover both.
