    [gdb/testsuite] Fix gdb.server/unittest.exp for remote target
    
    With test-case gdb.server/unittest.exp and a build with --disable-unit-tests I
    get:
    ...
    (gdb) builtin_spawn /data/vries/gdb/leap-15-4/build/gdbserver/gdbserver \
      --selftest^M
    Selftests have been disabled for this build.^M
    UNSUPPORTED: gdb.server/unittest.exp: unit tests
    ...
    but with target board remote-stdio-gdbserver I get instead:
    ...
    (gdb) builtin_spawn /usr/bin/ssh -t -l vries localhost \
      /data/vries/gdb/leap-15-4/build/gdbserver/gdbserver --selftest^M
    Selftests have been disabled for this build.^M
    Connection to localhost closed.^M^M
    FAIL: gdb.server/unittest.exp: unit tests
    ...
    
    Fix this by making the regexp less strict.
    
    Tested on x86_64-linux.
