sudo: add test-version.sh and stop running sudo in tests

PKG_VERSION substitutes p->_p (1.9.17_p2) for a valid apk version, but the
binaries print the real 1.9.17p2, so the generic per-executable version
probe reports "no executables provided version" and fails. Add a
test-version.sh that matches the version string compiled into the binary.

Executing sudo under QEMU emulation (e.g. mips_24kc) hangs indefinitely, so
neither test-version.sh nor test.sh runs it any more: the version is read
from the binary and test.sh only checks the installed files.
