Revert "systemd: Fix timeouts mounting swap partitions and other devices"
This reverts commit 3e2f0a3405d13421acd9780f1a1d3678d0a672bb.
Instead, it uses systemd's conf.d/ feature to achieve this, rather than having to carry a bunch of gnarly patches.
Uses 30s for start timeouts and 10s for stop timeouts.
Also changes to use a compile-time default of 30s in timeouts (instead of the default of 5s).
