gssdp: check opengl is enabled or not

The sniffer PACKAGECONFIG will make gssdp depend on gtk4 as below.
PACKAGECONFIG[sniffer] = "-Dsniffer=true,-Dsniffer=false,gtk4,"

But gtk4 needs the opengl DISTRO_FEATURES enabled, so also check
opengl in gssdp recipe to keep consistent.

Fixes:
  ERROR: Nothing PROVIDES 'gtk4' (but /build/layers/meta-openembedded/meta-multimedia/recipes-connectivity/gupnp/gssdp_1.4.0.1.bb DEPENDS on or otherwise requires it)
  gtk4 was skipped: missing required distro feature 'opengl' (not in DISTRO_FEATURES)
  ERROR: Required build target 'meta-world-pkgdata' has no buildable providers.
  Missing or unbuildable dependency chain was: ['meta-world-pkgdata', 'gssdp', 'gtk4']
