Don't initialize RA library in svnversion.
Don't initialize RA library in svnversion.

svnversion doesn't directly depend on libsvn_ra, so using symbols from it
causes link failures on some platforms.  svnversion doesn't actually
use the RA layer, so there is no need to initialize it.  Note that
calling svn_ra_initialize() isn't required anyway for compatibility
reasons.

* subversion/svnversion/main.c Don't include svn_ra.h.
  (main): Don't call svn_ra_initialize().
