fix(desktop): keep the advertised apt suite pattern valid in v-mode

The start_build_computer apt `suite` pattern, added after #10423's base,
had an unescaped / inside a character class, which the v flag refuses.
The full-profile guard from #10423 caught it. Spell it \x2f, as the
same pattern already spells -.
