kib abd1094f17 Fix misuse of the kernel map in miscellaneous image activators.
Vnode-backed mappings cannot be put into the kernel map, since it is a
system map.

Use exec_map for transient mappings, and remove the mappings with
kmem_free_wakeup() to notify the waiters on available map space.

Do not map the whole executable into KVA at all to copy it out into
usermode.  Directly use vn_rdwr() for the case of not page aligned
binary.

There is one place left where the potentially unbounded amount of data
is mapped into exec_map, namely, in the COFF image activator
enumeration of the needed shared libraries.
