Jacopo Mondi d327a224ba tools: gpio: Print error string on IOCTL failures ...

Add to error messages the error description by concatenating
output of strerror() function to error messages print out by
gpio-utils.c on IOCTL failures.
Rationalize error messages, while at there, making all of them
look the same.
