[image/sifts] Add missing 'lib' in INSTALLATION_DIRS

While here, update obsolete DOXYGEN_PLIST_DIR -> DYNAMIC_PLIST_DIRS.
[hardware/velodyne-libs] Fix DEPEND_ABI in depend.mk

After d47fecb bumping hardware/velodyne-genom to 1.3 (hi Artur ;), the
requirement on velodyne-libs is >=0.6. Sync DEPEND_ABI with this.
[image/viam-libs] Update to 1.12

Changes since 1.11:
. Fix signed vs. unsigned char and opencv IplImage vs. private IplImage
. Add missing IPL_DEPTH_32F definition in case of disabled opencv support
. Split the .pc file into opencv-dependant and -independant parts
. Fix a %d format for size_t (via a cast to unsigned)
. Fix OPENCV_LIBS for some opencv distributions (with broken .pc)
[image/viam-genom] Update to 1.10

Changes since 1.9:
        41. Drop useless EXTRA_INCLUDES/LIBS in codels Makefile
        40. Fix require: and codels-require: fields

Changes in the package:
 . Fix dependencies: the codels require viam-libs~opencv, which in turn
   requires opencv (the latter cannot be tracked by viam-libs/depend.mk because
   of the optional nature of the option)

 . Properly track interface dependencies in the depend.mk (namely: viam-libs +
   pom-genom).

 . Add a version check against the viam.pc file in the depend.mk
Added more system package hints for Gentoo-like distribs
