kernelshark: Remove trace-cmd from the kernelshark package

kernelshark: Remove trace-cmd from the kernelshark package

Fixes [YOCTO 6550]

Images installing both trace-cmd and kernelshark would fail with:

error: file /usr/bin/trace-cmd conflicts between attempted installs of
kernelshark-1.2+git0+7055ffd37b-r3.core2_32 and
trace-cmd-1.2+git0+7055ffd37b-r3.core2_32

This patch removes ${bindir}/trace-cmd from the install prior to
packaging, as is already done with the ${datadir}.
