    scripts/mksysmap: drop the MODULE_INFO() symbols from kallsyms

    Commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped")
    keeps .modinfo symbols out of System.map and kallsyms, which assumes unique
    IDs have a format like '__UNIQUE_ID_modinfo123'.

    However, commit afb026b6d35c ("compiler: Tweak __UNIQUE_ID() naming"), sent
    in the same cycle, changes this to '__UNIQUE_ID_modinfo_123'.

    As a result this regexp has never matched and every kernel since v6.18 has
    carried one kallsyms entries for every MODULE_INFO() declaration in the
    kernel whether the modules are compiled or not.

    That's 5,810 entries for an x86 defconfig build and 15,200 for arm64.

    On x86 defconfig that is 113 KiB of kallsyms tables and 32 KiB of bzImage,
    and every lookup walks past them.

    Fix the pattern.
