refactor(userspace/coreutils): improve uname command
The IEEE Std 1003.1-2024 specifies this for output: By default, the output shall be a single line of the following form: "%s\n", <sysname> If the -a option is specified, the output shall be a single line of the following form: "%s %s %s %s %s\n", <sysname>, <nodename>, <release>, <version>, <machine> Additional implementation-defined symbols may be written; all such symbols shall be written at the end of the line of output before the <newline>. If options are specified to select different combinations of the symbols, only those symbols shall be written, in the order shown above for the -a option. If a symbol is not selected for writing, its corresponding trailing <blank> characters also shall not be written. Signed-off-by: EnderIce2 <enderice2@protonmail.com>
