    varnishtest: make process -expect-text on the same scale as vX
    
    Currently on process pX -expect-text varnishtest uses at most
    300000 us pauses. This make it offscale when compared on what
    varnish vX -expect does by trying 50 times with 100us pause
    in a total of 5s.
    
    Chaning term_expect_text() wait 3s before failing avoid tests
    to cause false positive under stress (i.e.: r02990) but putting
    process pX -expect-text and varnish vX -expect at the same time
    scale.
