memlayout: Ensure TIMESTAMP() region is big enough to avoid BUG()

The timestamp code asserts that the _timestamp region (allocated in
    memlayout for pre-RAM stages) is large enough for the assumptions it
    makes. This is good, except that we often initialize timestamps
    extremely early in the bootblock, even before console output. Debugging
    a BUG() that hits before console_init() is no fun.

This patch adds a link-time assertion for the size of the _timestamp
    region in memlayout to prevent people from accidentally running into
    this issue.
