tools/power turbostat: Fix delimiter bug in print functions

Commands that add counters, such as 'turbostat --show C1,C1+'
display merged columns without a delimiter.

This is caused by the bad syntax: '(*printed++ ? delim : "")', shared by
print_name()/print_hex_value()/print_decimal_value()/print_float_value()

Use '((*printed)++ ? delim : "")' to correctly increment the value at *printed.
