[Error] Trailing slash makes custom home dir incorrect

[callb4ck]

To Reproduce:
Simply create a new new container, but when specifying a custom home, put a trailing forward slash.

For example, do not use "/somepath/customhome" but use "/somepath/customhome/"

In my exact case

1. distrobox create -i alpine:latest -n test1 -H /home/sec/test/ --verbose &> output.log
2. distrobox enter test1

At this point $HOME will be "/home/sec/test/" and not "/home/sec/test", which means that every script that relies on $HOME is now compromised.
This will usually result something such as "$HOME/somepath" expanding into "/home/sec/test//somepath ".

Expected behavior:
$HOME should not have a trailing forward slash and every software relying on $HOME should work correctly.

Logs:
The file output.log along with a podman.log produced with podman logs test1 > podman.logs are atttached:
output.log
podman.log

Desktop:

• Podman 5.2.3
• Distrobox 1.7.2.1 installed trough rpm-ostree (system package manager and system repo)
• Host system: Fedora Silverblue 40
