kallsyms: remove unused arch_get_kallsym() helper
The arch_get_kallsym() function was introduced so that x86 could override
it, but that override was removed in bf904d2762ee ("x86/pti/64: Remove
the SYSCALL64 entry trampoline"), so now this does nothing except causing
a warning about a missing prototype:
kernel/kallsyms.c:662:12: error: no previous prototype for 'arch_get_kallsym' [-Werror=missing-prototypes]
662 | int __weak arch_get_kallsym(unsigned int symnum, unsigned long *value,
Restore the old behavior before d83212d5dd67 ("kallsyms, x86: Export
addresses of PTI entry trampolines") to simplify the code and avoid
the warning.
