useradd-staticids: skip recipes without static IDs

When enabling useradd-staticids.bbclass, one has to define static IDs
for all recipes in a world build, otherwise those without static IDs
generate parse errors or warnings, depending on USERADD_ERROR_DYNAMIC.

Defining unused IDs is a lot of work and clutters the passwd/group
file of a distro.

Distros which want to avoid this can now set USERADD_ERROR_DYNAMIC =
"skip" and recipes which would have triggered a message then silently
get disabled. Only trying to build them shows the error message:

$ bitbake apt
...
ERROR: Nothing PROVIDES 'apt'
ERROR: apt was skipped: apt - apt: username _apt does not have a static ID defined.
