Add flag to UnphiMojo that adds +tests meta to XMIR

[maxonfjvipon]

Here we get the situation where +tests meta is not transfered to XMIR while unphi stage.
The solution is to add flag to UnphiMojo that adds such meta.
Then we also need to add such flag to eoc

@maxonfjvipon maybe we can make it possible to add different metas (like +package, etc):

mvn eo:unphi "-Deo.unphiMeta=+tests" "-Deo.unphiMeta=+package" "-Deo.unphiMeta=+architect yegor"

[maxonfjvipon]

@yegor256 +package is converted to phi as an object with lambda

[yegor256]

@maxonfjvipon let's prohibit the usage of +package, but others may be necessary to use in the future. It would be great to make it possible now.
