Update property retrival method

[ Merge of http://go/wvgerrit/70203 ]

The earlier property_get() method had a limitation on property length.
Properties of some new devices exceed that length. An error message
is returned rather than a truncated string. Replace its use with
android::base::GetProperty() which does not have a length limitation.
