Kernel: Fix enum of sysconf values to be in the correct order

Browse source 
This prevented from dmidecode to get the right PAGE_SIZE when using the
sysconf syscall.

I found this bug, when I tried to figure why dmidecode fails to mmap
/dev/mem when I passed --no-procfs, and the conclusion is that it tried
to mmap unaligned physical address 0xf5ae0 (SMBIOS data), and that was
caused by a wrong value returned after using the sysconf syscall to get
the plaform page size, therefore, allowing to send an unaligned address
to the mmap syscall.
