Amos Kong 01ba660fe7 sysconfig: correct the assignment in env file of systemd
This commit e80a5e3cb3 introduced an issue,
it wrongly passes an empty string to scylla-jmx cmdline, which causes
scylla-jmx script stuck. The cmdline real executes is:

  # scylla-jmx -l /usr/lib/scylla/jmx ""

Wrapped quotation marks of env variable can't be parsed away if we use
${SCYLLA_PARAMS} in ExecStart cmdline, but $SCYLLA_PARAMS works.

Another problem is the variable can't be re-used insider env file,
reference: [1]. Let's split the parameters to multiple env variables,
and combine them in ExecStart cmdline.

Fixes scylladb/scylla#2935
