Description of problem:

When microdnf is running in fedora-minimal container, that has POSIX locale by default, an escape sequence is printed instead of a non-breaking space in the Size column.
microdnf uses g_format_size(), that inserts non-breakable space.
From https://docs.gtk.org/glib/func.format_size.html
> The returned string is UTF-8, and may use a non-breaking space to separate the number and units, to ensure they aren’t separated when line wrapped.

If I change the locale to C.utf8 in the container, it works as expected.
Given that microdnf main purpose is to run in containers, specifically in fedora-minimal that defaults to POSIX locale, it would be good to produce human readable output by default.

Version-Release number of selected component (if applicable):
microdnf-3.8.0-2.fc35.x86_64

Steps to Reproduce:
1. podman run -ti fedora-minimal:35 
2. microdnf install vim

Actual results:
$ podman run -ti fedora-minimal:35 
bash-5.1# microdnf install vim
