loader: fix endianness conversion

r328536 broke symbol loading on amd64 at least (and probably other
arches). r328826 contained the problem to ppc only by adding
pre-processors guards.

Fix this properly by moving the endianness conversion to separate
helper functions, and make the conversion more robust by using sizeof
instead of having to manually code the size of each field.

Finally list the fields in each structure in a macro in order to avoid
code repetition.

The cross-endian loader change in r328536 (review D12422) broke symbol
loading on (at least) amd64 kernels. Temporarily paper over the issue
by restricting the cross-endian support to only powerpc, until a proper
fix arrives.

loader: support for mixed-endianness ELF/loader and POWER8

On POWER8 with current petitpoot, the loader.kboot might be
run as little-endian application. The FreeBSD kernel is
always big-endian, so the load_elf_* routines must be aware
of proper endianness of all fields.

Prefer stdint.h to inttypes.h since the added prototypes form the
latter aren't used. Prefer sys/link_elf.h to link.h so we're only
dependent on the kernel tree. The default installation of link.h just
includes this file, and any benefit from that is outweighed by the
hassle it causes. This reduces the footprint of files needed from the
system includes (or sysroot in buildworld).

Fix theoretical integer overflow issues. If the product here is
greater than 2^31-1, then the result will be huge. This is unlikely,
as we don't support that many sections, but out of an abundace of
caution cast to size_t so the multiplication won't overflow
mysteriously when size_t is larger than 32-bits. The resulting code
may be a smidge larger, but this isn't super-space critical code.
