linux-user: Remove support for CRIS target

As per the deprecation notice in commit c7bbef4023:

  The CRIS architecture was pulled from Linux in 4.17 and
  the compiler is no longer packaged in any distro making
  it harder to run the `check-tcg` tests. Unless we can
  improve the testing situation there is a chance the code
  will bitrot without anyone noticing.
