mambo: Match whole string when looking up symbols with linsym/skisym

linsym/skisym use a regex to match the symbol name, and accepts a
partial match against the entry in the symbol map, which can lead to
somewhat confusing results, eg:

  systemsim % linsym early_setup
  0xc000000000027890
  systemsim % linsym early_setup$
  0xc000000000aa8054
  systemsim % linsym early_setup_secondary
  0xc000000000027890

I don't think that's the behaviour we want, so append a $ to the name so
that the symbol has to match against the whole entry, eg:

  systemsim % linsym early_setup
  0xc000000000aa8054
