MDL-55987 gradebook: Claim extra memory when updating final grades

Browse Source 
As we experienced in a bigger moodle.org course (7500 users, 70 grade
items), the standard memory limit 256M may not be enough here. We were
not able to find any obvious memory leak in the processing. Requiring
extra memory helped in this particular case and it seems reasonable to
have it in the core.
