Android: accept both spaces and tabs separators for env vars and args

The requirement for separating the app args by tabs only is not
justified, since the the args are passed as a string to C++ where
QProcess::splitCommand() is used to get a list of single args and
that knows how to handle the parsing properly anyway.

As for env vars, QtLoader currently expects env vars to be separated
by tabs only, however, to account for different use cases, it should
handle both tabs and spaces.
