scripts/sorttable: Mark long_size as __maybe_unused

Browse Source 
When building in a kernel tree prior to commit b055f4c431 ("sorttable:
Move ELF parsing into scripts/elf-parse.[ch]") with clang-23 or newer,
which implements a new warning under -Wunused-but-set-variable for
static global variable, there is a warning from sorttable because
long_size is unused when MCOUNT_SORT_ENABLED is not set:

  scripts/sorttable.c:452:12: error: variable 'long_size' set but not used [-Werror,-Wunused-but-set-global]
    452 | static int long_size;
        |            ^

Mark long_size as __maybe_unused to avoid inserting more ugly #ifdef
directives while insuring the warning does not reappear, as the
aforementioned change does not alter the uses of long_size, so it
appears to be coincidence that the warning disappears after this
refactoring.
