Subject: perf top: Use __fallthrough

From: Arnaldo Carvalho de Melo <acme@redhat.com>

commit 7b0214b702ad8e124e039a317beeebb3f020d125 upstream.

The implicit fall through case label here is intended, so let us inform
that to gcc >= 7:

    CC       /tmp/build/perf/builtin-top.o
  builtin-top.c: In function 'display_thread':
  builtin-top.c:644:7: error: this statement may fall through [-Werror=implicit-fallthrough=]
      if (errno == EINTR)
         ^
  builtin-top.c:647:3: note: here
     default:
   ^~~~~~~
