AndroidTarget: Fix ps when NAME column contains spaces

Targets have been observed where `ps` output contains entries with NAME columns
of the form "[foo bar]". This means the `parts` list is too long and the PsEntry
call reports too many arguments. Since NAME is the rightmost column, just fix
the number of entries we recognise to 8.
