app/vmselect/promql: substitute rollupFuncsCannotAdjustWindow with rollupFuncsCanAdjustWindow
The list of functions, which can adjust lookbehind window is more limited than the rest of functions,
so it is better from maintainability and readability PoV using the allowlist instead of blocklist.

app/vmselect/promql: return back the behaviour for deriv() function when the lookbehind window doesnt contain enough points
It is expected that the `deriv(m[d])` returns non-empty value if the lookbehind window `d`
contains less than 2 samples in the same way as `rate()` does.

This is a follow-up after 3e084be06b .

app/vmselect: make predict_linear and deriv compatible with Prometheus (#1681)
Previously, `predict_linear` returned slightly different results comparing
to Prometheus. The change makes linear regression algorithm compatible
with Prometheus.

`deriv` was excluded from the list of functions which can adjust the time
window for the same reasons.

app/vmselect: fix binary comparison func (#1667)
The fix makes the binary comparison func to check for NaNs
before executing the actual comparison. This prevents VM
to return values for non-existing samples for expressions
which contain bool comparisons. Please see added test
for example.
