[PATCH 11/22] tools/perf/tests: Fix shellcheck warning for asm_pure_loop.sh shell script

[Athira Rajeev]

From: Kajol Jain <kjain at linux.ibm.com>

Running shellcheck on asm_pure_loop.sh throws below warning:

In coresight/asm_pure_loop.sh line 8:
. $(dirname $0)/../lib/coresight.sh
  ^-----------^ SC2046 (warning): Quote this to prevent word splitting.

Fixed the warning by adding quotes to avoid word splitting.

ShellCheck result with patch:
    # shellcheck -S warning coresight/asm_pure_loop.sh
    #
