infra: fix per-target coverage html generation (#7927) 

* infra: fix per-target coverage html generation

When generating coverage reports for single targets we should not
include all fuzz targets (in the $objects var), but only the object
(binary file) for the given target.

Ref: https://github.com/ossf/fuzz-introspector/issues/340

* coverage: remove potential race condition
