Under jailer, readdir/stat on / can stall the UI via /proc and /sys. Do not offer "/" as a drive, redirect root back to the safe drive list, and skip virtual FS nodes if root is enumerated.

Summary
On webOS, RetroArch runs under jailer. Opening Load Content and selecting filesystem root (
/), or navigating Parent Directory up to/, can freeze the UI. Under the jail, directory enumeration touches virtual filesystems such as/procand/sys, which stalls the main thread.This change keeps the file browser on safe storage locations and refuses to treat
/as a normal browsable directory on webOS.Changes
