fix(scheme/itimer): wrong chunk size
...
Chunk size of the scheme (`size_of::<ITimerScheme>() == 0`) was being
provided instead of `size_of::<ITimerSpec>()`. This resulted in a kernel
panic (division by zero) when kread was called for this scheme.

fix(mremap): fix referencing
...
Before it was first add_ref'ed by `borrow_frame_enforce_rw_allocated`,
manually and then by `allocated_shared_one_page`.
Now it is only done by `borrow_frame_enforce_rw_allocated` and does not
get unref-ed as take() is called on the returned `RaiiFrame`.
Now the page is manually mapped and an `Allocated` type grant is
constructed (synonymous to `MAP_PRIVATE`). Before by using `allocated_shared_one_page`
an `AllocatedShared` provided grant was constructed (synonymous to
`MAP_SHARED`), which was wrong as the TCB would've not got CoW-ed
after fork(), making the Tcb malformed.
