selftests/mm: rename pkey register macro

Browse Source 
PKEY_ALLOW_ALL is meant to represent the pkey register value that allows
all accesses (enables all pkeys).  However its current naming suggests
that the value applies to *one* key only (like PKEY_DISABLE_ACCESS for
instance).

Rename PKEY_ALLOW_ALL to PKEY_REG_ALLOW_ALL to avoid such
misunderstanding.  This is consistent with the PKEY_REG_ALLOW_NONE macro
introduced by commit 6e182dc9f2 ("selftests/mm: Use generic pkey
register manipulation").
