[dev.fuzz] internal/fuzz: count coverage-only runs toward -fuzztime

When we start fuzzing, we gather baseline coverage by calling the fuzz
function with each entry in the corpus (testdata, F.Add, and
cache). These calls should count toward -fuzztime when it specifies a
limited number of calls to the fuzz function.
