The perf probe related tests like probe_vfs_getname.sh which
is in "tools/perf/tests/shell" directory have dependency on
debuginfo information in the kernel. Currently debuginfo
check is handled by skip_if_no_debuginfo function in the
file "lib/probe_vfs_getname.sh". skip_if_no_debuginfo function
looks for this specific error log from perf probe to skip
the testcase:

<<>>
Failed to find the path for the kernel|Debuginfo-analysis is
not supported

But in some case, like this one in powerpc, while running this
test, observed error logs is:

The /lib/modules/<version>/build/vmlinux file has no debug information.
Rebuild with CONFIG_DEBUG_INFO=y, or install an appropriate debuginfo
package.
  Error: Failed to add events.

Update the skip_if_no_debuginfo function to include the above
error, to skip the test in these scenarios too.
Patch looks good to me.
