tools/nolibc: stop rounding malloc() sizes up to 4096 bytes

malloc() rounds the size of each mapping up to a multiple of 4096,
presumably to align it to a page boundary. But the page size is not 4096
on all architectures, and mmap() and munmap() round the length up to the
page size themselves.

Drop the rounding. As heap->len is no longer rounded up, growing a block
with realloc() now always creates a new mapping.
