media-tv/v4l-utils: patch for -fno-common bug

Reused the patch already used for media-libs/libv4l.

Applied to ebuilds 1.16.6 (last stable) and 1.18.0 (not stabilized).
No revision bump as this is a trivial build failure treatment.

Bug: https://bugs.gentoo.org/706834
Package-Manager: Portage-2.3.66, Repoman-2.3.16
