Avoid performing a potentially-blocking malloc for kenv lookups that will only perform non-destructive integer conversions on the returned buffer. Instead, perform the strtoq() in-place with the kenv lock held. PR: 248250

Avoid performing a potentially-blocking malloc for kenv lookups that will only perform non-destructive integer conversions on the returned buffer. Instead, perform the strtoq() in-place with the kenv lock held. While here, factor the logic around kenv_lock acquire and release into kenv_acquire() and kenv_release(), and use these functions for some light cleanup. Collapse getenv_string_buffer() into kern_getenv(), as the former no longer has any other callers and the only additional task performed by the latter is a WITNESS check that hasn't been useful since r362231.
