On Android-x86 (or BlissOS) it initialize Android by using switch_root or chroot, when checking a path with dentry_path_raw() it will show the whole real path instead of the path that we want.

Relax the checking requirement by using strstr to look for "/system/packages.list" in the string instead of requiring the path to be "/system/packages.list"

This fixes #1783

Isn't this potentially exploitable?
e.g., /sdcard/i_am_evil/system/packages.list

Are there anything sensitive in /system/packages.list in perspective of KernelSU?
