build: fix installation when only modules in subdirs are enabled

In case only modules that are built in subdirectories of extensions
are enabled (and thus nothing is build in extensions directory itself)
installation fails with the error (only build_ACCOUNT=y in mconfig):

install -pm0755
"/vt/portage/tmp/portage/net-firewall/xtables-addons-1.21/image/
//usr/local/libexec/xtables";
install: missing destination file operand after
"/vt/portage/tmp/portage/net-firewall/xtables-addons-1.21/image/
//usr/local/libexec/xtables"
Try `install --help' for more information.
