Man pages: refactor common options: --env 

Only among podman create, exec, run. The same option in
podman build, generate-systemd, and secret-create is too
different.

Should be a trivial one to review, the only difference is
a period at the end of one sentence. And, of course, the
"See Environment note" applies only to podman-create and
run, not exec, so it can't be deduplicated.

#### **--env**, **-e**=*env*
Set environment variables.
This option allows arbitrary environment variables that are available for the process to be launched inside of the container. If an environment variable is specified without a value, Podman will check the host environment for a value and set the variable only if it is set on the host. As a special case, if an environment variable ending in __*__ is specified without a value, Podman will search the host environment for variables starting with the prefix and will add those variables to the container.
