Remove unnecessary linux/limits.h include

None of the files affected use any macros from linux/limits.h:

    $ git grep -Fl 'NGROUPS_MAX
    ARG_MAX
    LINK_MAX
    MAX_CANON
    MAX_INPUT
    NAME_MAX
    PATH_MAX
    PIPE_BUF
    XATTR_NAME_MAX
    XATTR_SIZE_MAX
    XATTR_LIST_MAX
    RTSIG_MAX' -- src
    src/firejail/cmdline.c
    src/firejail/firejail.h
    src/libtrace/libtrace.c
    src/libtracelog/libtracelog.c

Environment:

    $ grep '^NAME' /etc/os-release
    NAME="Artix Linux"
    $ pacman -Qo /usr/include/linux/limits.h
    /usr/include/linux/limits.h is owned by linux-api-headers 5.12.3-1

Note: This include has been present on all of the affected files since
their inception.  For restrict_users.c, that's on commit 4f003daec
("prevent leaking user information by modifying /home directory,
/etc/passwd and /etc/group") and for every other file, it's on commit
137985136 ("Baseline firejail 0.9.28").

Relates to #4578.
