fix error

i got this error on archlinux when trying to run obs via flatpak:

bwrap: can't make symlink at /var/run: File exists

/media which is normally a real directory on archlinux to be a symlink to /var/run/media, replacing /media with a symlink to /run/media seems to fix the issue, before running the following command make sure you don't have any external drive mounted.

mount |grep media

if you see any output with previous command, umount the device, then proceed.

rm -rf /media 
rm -rf /var/run/media
mkdir /run/media
ln -s /run/media /media
