tools lib traceevent: Check for spaces in character array
Currently when using the raw format for fields, when looking at a
character array, to determine if it is a string or not, we make sure all
characters are "isprint()". If not, then we consider it a numeric array,
and print the hex numbers of the characters instead.
But it seems that '\n' fails the isprint() check! Add isspace() to the
check as well, such that if all characters pass isprint() or isspace()
it will assume the character array is a string.
