[ptxdist] [PATCH v2] setlocalversion: replace echo -n with printf

["Andreas Bießmann" <andreas@biessmann.de>]

On some systems the 'echo -n "$v"' lead to corrupted
$PTXDIST_VERSION_FULL cause the builtin echo is used which does not know
about -n switch. Instead of just removing the -n switch use printf as
the rest of this script do.

Before this patch my version looks like this:

---8<---
$ ptxdist --version
-n 2011.12.0-00047-g9849e20
--->8---

changes since v1:
 - stay at /bin/sh
 - replace echo -n by printf as suggested by Marc Kleine-Budde

I tested a .tarball-version with trailing newline and it worked at least for my
/bin/sh (OS X Lion)
