pngoverlay-cairo utility now in woofQ

EasyOS, and older pups, have the 'pngoverlay' utility, which overlays two 48x48 PNG images. We use it to create the "close box" on the partition icons on the desktop.

/usr/sbin/pngoverlay is written in BaCon, and has been very troublesome. It requires the executable to be in the same folder as the icons, if build it in OE, a cross-compile environment, it compiles but segfaults when try to use it. It changes the "PWD" variable, that I commonly use in scripts -- that one took me by surprise!

We also have /usr/sbin/pngoverlay.sh, that uses 'netpbm' utilities. It was broken but I fixed it in 2020.

Mick (01micko on the forum) has written two replacements in C, 'pngoverlay-gtk' and 'pngoverlay-cairo'. I am now retiring the BaCon 'pngoverlay' and using Mick's 'pngoverlay-cairo'. See info here:

As posted this morning, have recompiled everything in OE. Will add source package 'pngoverlay-cairo-20190623.tar.gz' to the build. The source package will be hosted on ibiblio.org soon.

I have modified these scripts in woofQ to recognize 'pngoverlay-cairo' and use it if exists. Just in case, the fallback will be to use 'pngoverlay' if doesn't exist:

rootfs-skeleton/usr/local/easy_containers/easy-containers
rootfs-skeleton/usr/sbin/icon_switcher_cli
rootfs-skeleton/usr/sbin/icon_switcher
rootfs-skeleton/usr/local/sfsget/dir2sfs
3buildeasydistro

Note, the BaCon 'pngoverlay' is in the 'pup-tools' package, will pull it out.
