[Buildroot] [git commit branch/2023.05.x] package/agentpp: fix build error due to type mismatch

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ca87e434b2f240c43f6cb6d9a94cc51004693c2a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.05.x

This was supposedly fixed by commit 5f06ecf5e151 ("package/agentpp:
security bump to version 4.6.0") but has kept happening so far.

No public place for contributions, thus this patch has been sent to private
e-mail.
