[PATCH v6 6/6] image_types_wic: gate syslinux-native on the target, not the build host

[Trevor Woerner <twoerner@gmail.com>]

A .wks needs the syslinux installer only when the target is x86.
image_types_wic.bbclass selects syslinux-native on the build host
architecture instead, so the dependency lands like this:

                 | x86 target | non-x86 target
    -------------+------------+----------------
    x86 host     | yes        | yes
    non-x86 host | no         | no

Two of those cells are wrong. An x86 image cross-built on a non-x86 host
gets the target bootloader without the installer that writes it, and an
x86 host building a non-x86 image builds an installer nothing uses.

Gate on the target, as wic-tools does [1]:

                 | x86 target | non-x86 target
    -------------+------------+----------------
    x86 host     | yes        | no
    non-x86 host | yes        | no

Bug 13276 [2] was an aarch64 host failing to build syslinux-native for
an ARM target, at a time when syslinux was x86-only in every variant. It
was closed in 2019 by gating on BUILD_ARCH [3]. Since 7273e131bfc7 [4]
only syslinux's target code is x86-specific, so a host gate is no longer
needed, and gating on the target keeps 13276's case fixed.

changes in v6:
- retitled with an image_types_wic prefix, which is now the only file it
  touches
- gate WKS_FILE_DEPENDS_DEFAULT with target-arch appends instead of the
  removed shared variable; wic-tools keeps the arch-gated DEPENDS it
  already had

changes in v5:
- new in v5
