linux-mod.eclass: fix use of variables for EAPI=7

Since EAPI 7, variables like "D" no longer have a trailing slash.
However, linux-mod_pkg_preinst relied on a traling slash.

Due to that, any EAPI=7 ebuilds using linux-mod eclass to install
kernel modules didn't run DEPMOD and weren't added to MODULESDB.
