mm/mseal: fix mseal documentation for 32-bit kernels
mseal.o is built only for 64-bit kernels, so 32-bit kernels fall back to
sys_ni_syscall() and return -ENOSYS rather than -EPERM.
Drop architecture description in mseal.rst, since the arch feature doc has
the latest state of mseal for each architecture.
Fix the CONFIG_MSEAL_SYSTEM_MAPPINGS typo in init/Kconfig.
