woeusb: add p7zip to runtime deps

* woeusb: add p7zip to runtime deps enable extra feature (#47982)

WoeUSB depends on presence of '7z` binary in the path to execute an extra step. 
As Windows 7's installation media doesn't place the required EFI bootloaders
in the right location, WoeUSB extracts them from the system image manually
using '7z' binary which it checks with 'command -v 7z'.
