[PATCH v2] KernelShark: Inherit libdir from Makefile

[sztsian@gmail.com]

From: "Ziqian SUN (Zamir)" <sztsian@gmail.com>

The trace-cmd makefile supports install lib into a different name like
lib64. Now this patch implemented the same in kernel-shark.

Change since v1: Drop the change of EXECUTABLE_OUTPUT_PATH and fix set
command to lower case.
