[abisym] Remove leading space in output.

  When abisym reports a symbol as found, it currently emits a leading
space. It does not do this when reporting a symbol as not found.

This patch removes the leading space.

	* tools/abisym.cc (main): Remove leading space from output.
	* tests/data/test-lookup-syms/test0-report.txt: Remove leading
	space from expected output.
	* tests/data/test-lookup-syms/test01-report.txt: Ditto.
	* tests/data/test-lookup-syms/test02-report.txt: Ditto.
	* tests/data/test-lookup-syms/test1-1-report.txt: Ditto.

This looks good to me and I have applied it to master.

I have just edited the short line of the commit log to prefix it with
"abysym:".

Thanks!

Cheers,
