ziomon: fix Makefile install step chown warnings

Since coreutils v9.1 commit 8f31074cb ("chown: warn about USER.GROUP")
chown utility now warns about using of wrong separator for USER and
GROUP options. This leads to warnings during intall step in ziomon:

$ make install
  INSTALL ziomon
  SED     ziomon/install
chown: warning: '.' should be ':': ‘root.root’
  SED     ziomon/install
chown: warning: '.' should be ':': ‘root.root’
  SED     ziomon/install
chown: warning: '.' should be ':': ‘root.root’

To fix those warnings use ':' as separator instead of '.'. With this
patch applied those warnings are no longer present.
