Logcatd: Add new properties control logcat file size and file count.

Browse source 
Logcatd has capability to output logs to filesystem with certain size
and certain file count, however file size is not configurable, fixed
as 1024 kbytes, file count is configurable, but original property
name didn't match the logcat parameter well.
This patch add interface rotate_kbytes and count into logcatd.rc.
rotate_kbytes used to control each logcat file size.
count is another alias for logd.logpersistd.size to control file number.

Bug: 133362078
Test: Can use logcat -r -n with configures
