chore: Drop use of anuvu/squashfs from workflow and doc.

After removing the anuvu/squashfs import we no longer need to build
or install libsquashfs1 from squashfs-tools-ng.

-
-Contrary to what the documentation in squashfs implies, squashtool and
-libsquash from squash-tools-ng need to be installed globally, as user specific
-path overrides aren't propagated into `make check`'s test envs.
-
-Thus, when you reach the step **install into mylocal="$HOME/lib"** from the squashfs guide, use the config below. You can put them at the end of your .bashrc file so you don't need to run them every time.
-
-    mylocal="/usr/local"
-    export LD_LIBRARY_PATH=$mylocal/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
-    export PKG_CONFIG_PATH=$mylocal/lib/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}
-
 Since the path **/usr/local** is owned by root, when you reach the step to run **make install**, you need to run it as **sudo**.
 
 `make check`  requires the **golangci-lint** binary to be present in $GOPATH/bin
