[CRIU] [PATCH] buld: generate tag with etags only if ctags failed

[Dmitry Safonov]

As I didn't set swap area on my computer - I do not use emacs.
So, lets generate tags with etags only if ctags did not do that.

Fixes the following error:
[criu]$ make tags
  GEN      tags
xargs: etags: No such file or directory
Makefile:176: recipe for target 'tags' failed
make: [tags] Error 127 (ignored)
