taskset: clarify that masks are always hex in man page 

The man page confusingly says that the mask is "typically"
hexadecimal, when in fact it is always hexadecimal.  Fix the
language, and provide an additional example with no leading "0x".

Also, provide an example using the --cpu-list option.

may specify more CPUs than are present. A retrieved mask will reflect only the
bits that correspond to CPUs physically on the system. If an invalid mask is
given (i.e., one that corresponds to no valid CPUs on the current system) an
error is returned. The masks are typically given in hexadecimal. For example,
error is returned. The masks may be specified in hexadecimal (with or without
a leading "0x"), or as a cpu list with the
