    Fix user-filters IT fixture for Maven 4 compatibility
    
    Maven 4 splits CLI -D values strictly into 
MavenSession.getUserProperties(); they no longer leak into 
getSystemProperties() as they did on Maven 3. The user-filters IT's ItFilter 
test fixture read getSystemProperties() only, so under Maven 4 it wrote 
'toto=null' and the post-build groovy assertion 'content.contains("toto=titi")' 
failed.
    
    Consult getUserProperties() first and fall back to getSystemProperties() so 
the fixture works on both Maven 3.9.x and Maven 4.0.0-rc-5+.
    
    Production plugin code is unchanged; the bug is only in the IT fixture.
    
    This unblocks PR #466 (enable Maven 4 CI matrix).
