[Buildroot] [PATCH v2 1/4] package/poco: add BR2_PACKAGE_POCO_ARCH_SUPPORTS

[Julien Olivain <juju@cotds.org>]

This change is motivated by a misalignment of the Kconfig package and
comment dependencies, introduced in commit 0737f48c5f "package/poco:
disable build for riscv" (BR_riscv was missing in the comment).
Introducing BR2_PACKAGE_POCO_ARCH_SUPPORTS solve this issue.

Signed-off-by: Julien Olivain <juju@cotds.org>

Changes v1 -> v2:
Suggested by Thomas:
  - introduce _ARCH_SUPPORTS to prevent duplicating dependency conditions
