Fix some rounding code for shared memory.
InitializeShmemGUCs() always added 1 to the value calculated for
shared_memory_size_in_huge_pages, which is unnecessary if the
shared memory size is divisible by the huge page size.
CreateAnonymousSegment() neglected to check for overflow when
rounding up to a multiple of the huge page size.
These are arguably bugs, but they seem extremely unlikely to be
causing problems in practice, so no back-patch.
