rpc-sys: packagelist: handle ABI versions in apk world properly

It was originally assumed that all entries in '/etc/apk/world'
would have ABI-versioned package names.  This turns out to be false,
and apk happily adds package names with or without the ABI version
suffix.  This causes the output from 'ubus call rpc-sys packagelist'
to exclude some packages from the user-installed package list,
thus causing them to disappear when doing an ASU build.

Fix it by checking both versioned and unversioned package names.
