Add a new condition wich checks against systemd version.
Change condition_test_kernel_version() into a generic condition_test_version()
so most of the code can be reused.
$ systemctl --version
systemd 258 (258~devel-g53ca5f6)
$ systemd-analyze condition 'ConditionVersion=systemd>255'
test.service: ConditionVersion=>255 succeeded.
$ systemd-analyze condition 'ConditionVersion=systemd>260'
test.service: ConditionVersion=>260 failed.
$ systemd-analyze condition 'ConditionVersion=systemd>=258'
test.service: ConditionVersion=>=258 succeeded.
$ systemd-analyze condition 'ConditionVersion=systemd>=257.1'
test.service: ConditionVersion=>=257.1 succeeded.
$ uname -r
6.12.13-200.fc41.aarch64
$ systemd-analyze condition 'ConditionVersion=kernel > 4.4'
test.service: ConditionVersion=kernel > 4.4 succeeded.
$ systemd-analyze condition 'ConditionVersion=kernel > 6.20'
test.service: ConditionVersion=kernel > 6.20 failed.
$ systemd-analyze condition 'ConditionVersion=kernel < 9.0'
test.service: ConditionVersion=kernel < 9.0 succeeded.
