You say 'var.names', but use 'varnames'. ?strip.custom also says:

var.name: vector of character strings or expressions as long as the

          number of conditioning variables.  The contents are
          interpreted as names for the conditioning variables.  Whether
          they are shown on the strip depends on the values of
          'strip.names' and 'style' (see below).  By default, the names
          are shown for shingles, but not for factors.

This seems to work as expected:

xyplot(1 ~ 1 | gl(1, 1),

       strip = strip.custom(var.name = expression(sqrt(Bray-Curtis)),
                            strip.names = TRUE, strip.levels = FALSE))
