Provide access to MSRs

Issue:

# \-> Disabled: Can't open fd for cpu0: Permission denied
# [...]RAPL uses the MSR kernel module to read model specific registers (MSRs) from user space. 
  To enable the msr module interface the admin needs to 'chmod 666 /dev/cpu/*/msr'.  
  For kernels older than 3.7, this is all that is required to use the PAPI RAPL component.[...]

Fix:

root@scirouter:~# usermod -aG <user> omp-bench
root@scirouter:~# make -C /var/yp
