kernel-shark: Show the standard error of kshark-record
When kshark-record fails, report the standard error which can be very useful
for debugging the issue that when wrong. For example, after removing the
kshark lib functions, instead of just having "Unknow error" print when
kshark-record dialog fails, I now get:
/usr/local/bin/kshark-record: error while loading shared libraries: libkshark-gui.so.0.9.8: cannot open shared object file: No such file or directory
