docs/manual: document $(FOO_PKGDIR)

Browse source 
In the manual, add a note that packages can use $(FOO_PKGDIR) to get the
path to the directory containg the .mk and Config.in files, if they need
it to e.g. copy files from there, like startup scripts, systemd units or
any other resource.

In the action definitions, you can use the following variables:
* +$(FOO_PKGDIR)+ contains the path to the directory containing the
+foo.mk+ and +Config.in+ files. This variable is useful when it is
necessary to install a file bundled in Buildroot, like a runtime
configuration file, a splashscren image...
* +$(@D)+, which contains the directory in which the package source
code has been uncompressed.
