Runtime option fix and minor changes

[Martin-Zeithaml]

1. The output of CEE_OPTIONS=tsocmd "OMVS RUNOPTS('RPTOPTS(ON)')" was not saved to due to error. The content of version_output was (missing the important part):

z/OS version: RELEASE z/OS 03.01.00 LICENSE = z/OS
Java version: java version "1.8.0_123"
NodeJS version: v18.24.0
External Security Manager: TSS
CEE Runtime Options: FSUM2051I The OMVS command failed because the display screen size is not supported.+
FSUM2052I The screen size must be at least 12 by 40 but less than 10000 bytes total.  The actual primary screen size is 255 by 255 (
65025 bytes).  The alternate screen size is 255 by 255 (65025 bytes).

2. version_output renamed to environment_output
3. Small change in help
4. If no SDSF, get the z/OS version from &SYSOSLVL
5. print_message_file to simplify the code

With fix, the output is like (some values might be altered):

[Environment information]
z/OS version: RELEASE z/OS 03.03.00 LICENSE = z/OS
Java version: java version "1.9.0_123"
NodeJS version: v22.00.01
External Security Manager: 007
CEE Runtime Options: OMVS RUNOPTS('RPTOPTS(ON)')
