tests/shell: Fix shellcheck SC1090 to handle the location of sourced files

Running shellcheck on some of the shell scripts throws
below error:

	In tests/shell/coresight/unroll_loop_thread_10.sh line 8:
	. "$(dirname $0)"/../lib/coresight.sh
	  ^-- SC1090: Can't follow non-constant source. Use a directive to specify location.

This happens on shellcheck version "0.6.0". Fix shellcheck
warning for SC1090 using "shellcheck source="i option to mention
the location of sourced files.
