lintian: fix init.d-script-missing-dependency-on-remote_fs
depending on adduser when using it in postinst
create /var/run/statsd on initscript runtime

creating the /var/run/statsd directory during the debian package installation
violates the lintian rule 'dir-or-file-in-var-run'. /var/run might be a tmpfs
and thus volatile.
install the initscript via update-rc.d

debian/postinst tries to remove it, so we need to install it first
fixing lintian rule 'script-in-etc-init.d-not-registered-via-update-rc.d'
bash syntax fix in init script
remove ${misc:Depends}, it's unnecessary

- this only got added because of a lintian error/warning which isn't thrown
  anymore (https://github.com/etsy/statsd/commit/4584ba61d97dd1f53e075bfb583e4ec5d8574ffd)
new debian version aligned with upstream 0.6.0-1
