Subject: [PATCH] main: Fixes an incorrectly constructed environment PATH
 resulting in failure to launch applications

While testing on Fedora 44, noticed that `_linux_parse_ip_link_show` was failing to run `ip link show`.

After investigating, it was because `/usr/bin` was being dropped off the PATH because the windows hack made the PATH look like: `/home/user/.local/bin:/home/user/bin:/usr/local/bin:/usr/bin;/usr/bin`.

That Windows PATH separator resulted in the `/usr/bin` folder not being usable on the PATH, and thus `ip link show` could not run.
