Subject: [PATCH] Debian: fix the bug of getting the dev's fd

Some pipe files are generated when assigning variables
and getting the process's fd, and are removed when done.
Since the pipe's fd is not the dev's fd, filter out the pipe fd.

Test Plan:
PASS: qemu iso installed successful
PASS: lab iso installed successful

Closes-Bug: 1991816
