waffle: fix REQUIRED_DISTRO_FEATURES and PACKAGECONFIG virtual/libgl dependencies

Waffle's REQUIRED_DISTRO_FEATURES statement looks into DEPENDS and if
virtual/libgl is present, it includes opengl as distro feature. However,
in a multilib environment, recipes provides virtual/${MLPREFIX}libgl,
thus waffle recipe needs to include the prefix. Also PACKAGECONFIG
statements need this change in order to properly include the libgl
dependency.

The way this error showed up was in a multilib environment and a distro
not containing opengl, i.e. nodistro, leading the following error when
building world -S none (because opengl was not included as required distro
feature):

    ERROR: Nothing PROVIDES 'virtual/lib32-libgl' (but virtual:multilib:lib32:/meta/recipes-graphics/waffle/waffle_1.5.2.bb DEPENDS on or otherwise requires it). Close matches:
      virtual/lib32-libsdl
      virtual/lib32-libc
      virtual/lib32-libsdl2
    ERROR: Required build target 'lib32-meta-world-pkgdata' has no buildable providers.
    Missing or unbuildable dependency chain was: ['lib32-meta-world-pkgdata', 'meta-world-pkgdata', 'lib32-waffle', 'virtual/lib32-libgl']

    Summary: There were 2 ERROR messages shown, returning a non-zero exit code.
