Jorropo 22b0ff05d4 Kernel: sys$mmap PAGE_ROUND_UP size before calling allocate_randomized (#5154) 
`allocate_randomized` assert an already sanitized size but `mmap` were
just forwarding whatever the process asked so it was possible to
trigger a kernel panic from an unpriviliged process just by asking some
randomly placed memory and a size non alligned with the page size.
This fixes this issue by rounding up to the next page size before
calling `allocate_randomized`.

Fixes #5149
