rust: fix build warning for unknown lint

Builds for suricata with rustc 1.24.1 give the warning:
	warning: unknown lint: `ellipsis_inclusive_range_patterns`

The builtin lint had been added to fix a deprecation warning
for the `...` range patterns. Although rustc 1.24.1 is
no longer the MSRV, rendering the lint unnecessary, removing it
results in a strict error for rustc 1.47.x.

Add relevant code to allow unknown lints.
