Unhardcode compression=lz4 when creating jails on ZFS

[jbeich]

I'd like to compress jails more aggressively with gzip, zstd or newer but poudriere forces lz4.

$ zfs get compression tank/poudriere/jails
NAME                  PROPERTY     VALUE           SOURCE
tank/poudriere/jails  compression  zstd-18          local

$ poudriere jail -cj 114amd64 -a amd64 -v 11.4-RELEASE

$ zfs get compression tank/poudriere/jails/114amd64
NAME                           PROPERTY     VALUE           SOURCE
tank/poudriere/jails/114amd64  compression  lz4             local

can we close this now?

By default, I get:

zbook/poudriere                   compression  on              local
zbook/poudriere/data              compression  on              inherited from zbook/poudriere
zbook/poudriere/data/.m           compression  on              inherited from zbook/poudriere
zbook/poudriere/data/cache        compression  off             local
zbook/poudriere/data/images       compression  on              inherited from zbook/poudriere
zbook/poudriere/data/logs         compression  on              inherited from zbook/poudriere
zbook/poudriere/data/packages     compression  off             local
zbook/poudriere/data/wrkdirs      compression  off             local
zbook/poudriere/jails             compression  on              inherited from zbook/poudriere
zbook/poudriere/jails/main        compression  on              local
zbook/poudriere/jails/main@clean  compression  -               -
zbook/poudriere/ports             compression  on              inherited from zbook/poudriere
zbook/poudriere/ports/default     compression  on              local

In practice (without suggesting these as defaults), I prefer:

% zfs get compression | grep poudriere
