[Buildroot] [PATCH 1/3] package/systemd: add option to enable SysV and utmp compatibility

[Norbert Lange]

The option BR2_PACKAGE_SYSTEMD_SYSV enables compatibility with SysV services-

BR2_PACKAGE_SYSTEMD_UTMP adds support for the utmp Database,
which is only used by tools like 'who' and 'last' nowadays AFAIK.
