Remove name length limit for system properties
Android O removes name length limit for system properties.
Use __system_property_read_callback instead of deprecated
__system_property_read in getprop and remove check for
property name length in setprop.
Test: adb shell setprop debug.test.very.very.long.property.name valueforpropertywithlongname
Test: adb shell getprop | grep debug.test.very.very.long.property.name
Bug: http://b/33926793
