Caused by the /usr/lib64/libreoffice/program/libfirebird_sdbclo.so which is in
main libreoffice package.
Based on ldd this one pulls firebird:
/usr/lib64/libreoffice/program/libfirebird_sdbclo.so
libfbclient.so.2 => /usr/lib64/libfbclient.so.2 (0x00007fe17314f000)
Needs to be moved to proper subpackage.
