alsaucm: Fix ending with quotes commands

If we use 'alsaucm -n -b -' with 'get "CapturePCM/Internal Mic"' then
the alsaucm will report error and stop immediately. The reason is that
the parse_line in usecase.c appends an empty argument if a command ends
with quotes.

This change adds a patch to fix the parse_line function in usecase.c.
