uemacs: remove unused functions

Commit 8fc7449 ("uemacs: fix sparse warnings, making file-local symbols
static.") made some functions that are not used anywhere static. This patch
removes them to kill the following compilation warnings:

  ansi.c:255: warning: ‘ansihello’ defined but not used
  ibmpc.c:505: warning: ‘ibmhello’ defined but not used
  vmsvt.c:521: warning: ‘hellovms’ defined but not used
  vt52.c:181: warning: ‘vt52hello’ defined but not used
