bsd-user: Simplify the implementation of execve
This removes the logic which prepends the emulator to each call to
execve and fexecve. This is not necessary with the existing
imgact_binmisc support and it avoids the need to install the emulator
binary into jail environments when using 'binmiscctl --pre-open'.

Merge tag 'bsd-user-for-9.1-pull-request' of gitlab.com:bsdimp/qemu into
staging
bsd-user: Misc changes for 9.1 (I hope)
V2: Add missing bsd-user/aarch64/target.h
This patch series includes two main sets of patches. To make it simple to
review, I've included the changes from my student which the later changes depend
on. I've included a change from Jessica and Doug as well. I've reviewed them,
but more eyes never hurt.
I've also included a number of 'touch up' patches needed either to get the
aarch64 building, or to implmement suggestions from prior review cycles. The
main one is what's charitably described as a kludge: force aarch64 to use 4k
pages. The qemu-project (and blitz branch) hasn't had the necessary changes to
bsd-user needed to support variable page size.
Sorry this is so late... Live has conspired to delay me.
