[bug] overrides for Puter PDE commands

[KernelDeimos]

PDEs are executable files that Puter runs in a Linux compatibility environment using v86. Some PDE files are hosted by the user admin and are meant to be used as commands in the terminal. However, app names currently override these executable file names and make it necessary to use the pderunner command with the full path of the file.

In Puter's terminal, this can be reproduced as follows:

• Run ls /admin/Public/bin
• Observe that sh.pde is present
• Try running sh - it opens an app instead
• Try running pderunner /admin/Public/bin/sh.pde - it works
