tools/power turbostat: Handle cap_get_proc() ENOSYS

[ Upstream commit d34fe509f5f76d9dc36291242d67c6528027ebbd ]

Kernels configured with CONFIG_MULTIUSER=n have no cap_get_proc().
Check for ENOSYS to recognize this case, and continue on to
attempt to access the requested MSRs (such as temperature).
