[RFA] fix thinko in sym info

[dje@google.com (Doug Evans)]

Hi.  I noticed this while testing a thinko of my own (blech).

asm-source.exp is now failing because it doesn't expect the offset
to be printed if its zero.
One could update the testcase, but the old behaviour is more user-friendly.

The outstanding question is, of course, whether

  "%s + %u", msym_name, offset

needs i18n.  This patch assumes it doesn't.

	* printcmd.c (sym_info): Don't print the offset if it's zero.
