[glib: 12/16] tests: Allow bitlock performance test to be smoketested

[Marco Trevisan <marcotrevi src gnome org>]

commit 419f882952153a2bc6fd1548b2c551531209f622
Author: Philip Withnall <pwithnall endlessos org>

    tests: Allow bitlock performance test to be smoketested
    
    Allow it to be run with a reduced iteration count when not run as `-m
    perf`, in order to check that the test still works.
    
    Previously it would do nothing when run without `-m perf`.
