[gentoo-dev] [PATCH] kernel-build.eclass: fix module signing with unspecified key

[Andrew Ammerlaan <andrewammerlaan@gentoo.org>]

MODULES_SIGN_KEY may be unset when using USE=modules-sign. Fix an issue
introduced in e290c3c78b7acb59393f46d1d15175d6dbfc77da that breaks this
configuration due to modules-sign-key.config not existing.
