[Sound-open-firmware] [PATCH v3] topology:scripts: fix tplg build script to compile last topology when using xargs

[Ranjani Sridharan]

When using xargs, the last topology file while batch processing alsatplg
doesn't get compiled properly.

Also remove a stray ; in the script.

Notes:
    Sending v3 as v2 was missed.
