acct-user.eclass: EAPI 8 support

Update the documentation to describe how to depend on GLEP 81
packages with EAPI 8.  There is no NSS module for resolving the
accounts installed in $SYSROOT,	so acct-* packages might also need
need to	be in $BROOT e.g. for fowners which directly calls chown.

  - BDEPEND so the build system	can resolve names when building
    packages in nonempty $SYSROOT at src_install time.

  - IDEPEND so the build system	can resolve names when installing
    binary packages in nonempty $ROOT at pkg_preinst time.

  - RDEPEND so the target system can use the accounts.
