[PATCH 1/2] trace-cmd: Fix the detection for swig

[sztsian]

From: Zamir SUN <sztsian@xxxxxxxxx>

The current detection for swig will cause output to be
/usr/bin/swig
y
So this will never be equal to y. With this patch, the swig path is
removed from output, so the detection can work as expected.

Fixes 3bf187a43b7e6302592552ecbc294e5820249687
