package/collectd: Fix build issue with SENSORS_API_VERSION >= 0x500

Current collectd version 5.7.1 fails to compile because there is a
check which breaks the compilation if lm_sensors API >= 0x500, but in
the mainline codebase this check was removed in commit:

  https://github.com/collectd/collectd/commit/069796bd76dd1ab0089a64f7c9c2a3c9f1475414

So add backported patch based on this commit.

Fixes:
