modif: rlimit: allow uppercase suffixes (#6890)

Browse source 
For better usability and because the proper suffixes (KiB, MiB and GiB)
are uppercase.

Affected commands:

* `rlimit-as`
* `rlimit-fsize`

Before:

    $ firejail --quiet --noprofile --rlimit-as=100m /bin/true
    $ firejail --quiet --noprofile --rlimit-as=100M /bin/true
    Error: invalid rlimit-as. Only use positive numbers and k, m or g suffix.: No such file or directory

After:

    $ firejail --quiet --noprofile --rlimit-as=100m /bin/true
    $ firejail --quiet --noprofile --rlimit-as=100M /bin/true

Relates to #4315.
