Update .Dt on these man pages: the kernel modules and corresponding man
pages are installed on more platforms than just i386.

Move man pages out of man4.i386. Most of them are applicable to amd64
too, so, instead of descending to the i386 directory, we add some magic to
the parent Makefile.
These man pages refer to drivers that I'm aware that work on amd64. Most
likely there are more, but I'll deal with them later.

- xref linsysfs
- improve the ldconfig part
- tell about pitfalls with the osrelease sysctl

Remove kern.elf32.can_exec_dyn sysctl. Instead extend Brandinfo structure
with flags bitfield and set BI_CAN_EXEC_DYN flag for all brands that usually
allow executing elf dynamic binaries (aka shared libraries). When it is
requested to execute ET_DYN elf image check if this flag is on after we
know the elf brand allowing execution if so.
