dropbear: fix build time warning

compiler complains in build log:
  svr-auth.c: In function 'checkusername':
  svr-auth.c:315:8: warning: extra tokens at end of #endif directive [-Wendif-labels]
   #endif HAVE_GETGROUPLIST
          ^~~~~~~~~~~~~~~~~

while this warning is harmless, let's fix it.
cherry-pick upstream commit 1ae4237920c3bd7f2fa6958d2a390f6693852285
