fix openssl(1) prime output

[Lawrence Teo]

When the openssl(1) prime command is asked to check the primality of a
decimal number, it changes it to hex in the output which is a little
confusing:

$ openssl prime 976110468996539
377C46DC41DBB is prime

The following diff fixes this so that it will always show the original
number in the answer:

$ openssl prime 976110468996539
976110468996539 is prime

Hex values explicitly specified with -hex remain unchanged:

$ openssl prime -hex 377C46DC41DBB
377C46DC41DBB is prime

ok?
