adguardhome: update to 0.107.0

Full changelog available at: https://github.com/AdguardTeam/AdGuardHome/releases/tag/v0.107.0

packr has been removed from build dependencies, per
https://github.com/AdguardTeam/AdGuardHome/commit/c6888326b034daea9e69de5ee0a8f37aede45892#diff-2873f79a86c0d8b3335cd7731b0ecf7dd4301eb19a82ef7a1cba7589b5252261L2

Also added the ability to configure working directory location and moved
the directory to /var. On most setups this should not change anything,
as /var is symlinked to /tmp. The move mostly benefits setups where /var
is configured to be persistent.

The working directory is used by AdGuard to store persistent data like
query logs, filter lists, etc.

Data stored in this directory can get really huge, as such allowing
this directory to be moved elsewhere (ie. an USB drive) is very
beneficial.
