[Android][REG] Packaging tool does not work with python 3.0+

1. command output is a bytes-like object in python3.0+,
re.findall can't use a string pattern on a bytes-like object,
encode the bytes-like object to str to fix that.
2. map function will return a map object in python3.0+,
'map' object has no attribute 'extend',
not use map function to fix that.

[Android] make_apk: Generated android name by package.

Try AppInfo.android_name is currently generated from options.name,
but the restrictions on options.name's value will be lifted in an upcoming commit.
That cannot happen to android_name,
so we now generate it from the package name passed via the --package option.
[Android] make_apk: Accept any string to be application name.

The new w3c manifest spec requires accepting any string to be application name.
However in previous make_apk process, they were treated as invalid input.
