fix(deploy/files): drop ProcSubset=pid from web reference unit

Browse source 
Mirrors ckn-bw fix: ProcSubset=pid hides /proc/sys/kernel/random/boot_id,
which journalctl needs at startup; web unit invokes journalctl for
live log streaming.

# It hides /proc/sys/kernel/random/boot_id which journalctl reads at

# live server logs into the UI. The server unit can keep ProcSubset=pid
# because srcds doesn't shell out to journalctl.
