package/poco: enable build for riscv64
riscv64 support was added upstream in commit:
https://github.com/pocoproject/poco/commit/26fa1b9e6bbe3a5d2d559d0e8bd5772a4e8fdfef
which is included in version >= 1.10.0.
Now, of the riscv architecture, only the 32-bit variant is not
supported, so change the arch restriction to that.
