Fix: statsd path in whilelist of native processes

This whitelist is used when calling Process.getPidsForCommands. That
method reads all pid directories under /proc and returns only those
which /proc/pid/cmdline matches the whitelist. Statsd returns
/system/bin/statsd in its cmdline and therefore was not included in the
results and ignored from reporting.

Bug: 116784348
Test: cat /proc/pid/cmdline for statsd
