After offline installation, scylla-jmx fails to be started for a chdir
error. WorkingDirectory is set to /var/lib/scylla in scylla-jmx.service,
it doesn't exist in nonroot install. This patch solved the problem by
setting WorkingDirectory to empty in nonroot.conf.

To install scylla-jmx using install.sh easily, we need:
- run dependency check before install
- run postinst script after install
But we don't want to run them when we build .rpm/.deb package,
we also need to add --packaging option to skip them.
See scylladb/scylla#5830
On the commit 4c8660d, we dropped /usr/lib/scylla/jmx since it likely no user
script invoke scripts under the directory.
However, we found there are possibility scylla-jmx.service tries to load .jar
file from /usr/lib/scylla/jmx, when user upgraded from older version of scylla.
Because /etc/sysconfig/scylla-jmx is marked as 'noreplace' on our rpm,
yum upgrade may keep old sysconfig file when it modified by user, that may
causes to load .jar from /usr/lib/scylla/jmx since we specify the path in the
sysconfig file.
To avoid the issue it's better to have symlinks on /usr/lib/scylla/jmx for
safety.
See #90
This is scylla-jmx part of https://github.com/scylladb/scylla/pull/5530
After we stopped replacing /usr/lib/scylla with symlink,
creating symlink on /opt/scylladb/scripts/jmx become meaningless,
so we can drop it now.
We able to introduce new symlink on /usr/lib/scylla, but it likely no user
directly invoke scripts under /usr/lib/scylla/jmx, so we don't have to
do that.
Since systemd unit can override parameters using drop-in unit, we don't need
mustache template for them.
Also, drop --disttype option on install.sh since it does not required anymore,
introduce --sysconfdir instead for non-redhat distributions.
Move package build script from .rpm/.deb to single script, install.sh.
We need this to support nonroot mode, and also to keep package build script
consistent between .rpm/.deb.
