qga: Shorten several error messages

Browse source 
Some, but not all error messages are of the form

    Guest agent command failed, error was '<actual error message>'

For instance, command guest-exec can fail with an error message like

    Guest agent command failed, error was 'Failed to execute child process “/bin/invalid-cmd42” (No such file or directory)'

Shorten this to just just the actual error message.  The guest-exec
example becomes

    Failed to execute child process “/bin/invalid-cmd42” (No such file or directory)
