Increase log source scanning frequency from 1s to 10ms

Increase log source scanning frequency from 1s to 10ms

This is workaround.  This commit ensures logs source is checked every 10ms.

In current design logs from source devices (/dev/log_) are checked
only periodically on fixed intervals (unlike other sources, which
are driven by epoll()).  The "special" android source handling seems
to be microoptimisation, done due to not entirely correct architecture
decisions.

Proper solution require adding android source devices to epoll.
