remove magic related warning for focal and bionic

[nikhil kshirsagar]

[IMPACT]

bionic and focal "sos report" command spews this warning on stderr
and sos defaults to an older approach for binary detection.

"
WARNING: Failed to load 'magic' module version >= 0.4.20 which sos aims
to use for detecting binary files. A less effective method will be used.
It is recommended to install proper python3-magic package with the
module.
"

This stderr output warning causes autopkgtests to fail for focal and bionic.

This patch avoids showing the warning since focal and bionic would anyway never get the python3-magic version needed (0.4.20) so there is no point warning about this and it's better simply to use to the older approach without checking for this version of python3-magic.

[WHERE PROBLEMS COULD OCCUR]

Since this patch avoid looking for python3-magic itself it may cause issues in sosreport in other places where there is an assumption about python3-magic having at least being attempted loading. I have however gone through the code and ruled this out, so this patch looks quite safe to me.

The patch looks good to me. Solves the false positive autopkgtest issue we discussed before.
