Enable memory-mapped coverage instrumentation
Bug: http://b/194128476
Bug: http://b/210012154
- pass -runtime-counter-relocation flag, which is needed to enable
memory-mapped coverage on Linux/Android.
- Include '%c' specifier in -fprofile-instr-generate compiler flag to
default to memory-mapped coverage.
- Disable continuous coverage if instrumentation is on for bionic/libc
(http://b/210012154).
Test: Run few coverage tests on Forrest.
