Use a default exclude filter for JaCoCo in Soong.

Instrumented builds should exclude certain classes from instrumenation
by default. (e.g. JaCoCo itself) Leverage the existing
DefaultJacocoExclusionFilter to do this.

Note: Two different default filters exist now (one for Make and one for
Soong), as they have different wildcard rules.

Test: EMMA_INSTRUMENT=true EMMA_INSTRUMENT_STATIC=true m -j32
TeleService and inspected the resulting temporary jar that was
instrumented to confirm that anything from org/jacoco was excluded.
