Fix database import script location (& whitespace)

[ChandlerSwift]

SUMMARY

Zabbix 3.0 (currently supported) and 3.2 (now unsupported) placed
import scripts at
/usr/share/doc/zabbix-server-{mysql,pgsql}-{3.0.0,3.2.0}/create.sql.gz,
while newer versions (3.4, 4.x, 5.x) have scripts at
/usr/share/doc/zabbix-server-{mysql,pgsql}/create.sql.gz.

References for currently supported versions:
3.0: https://www.zabbix.com/documentation/3.0/manual/installation/install_from_packages/server_installation_with_mysql#creating_initial_database
4.0: https://www.zabbix.com/documentation/4.0/manual/installation/install_from_packages/rhel_centos#importing_data
5.0: https://www.zabbix.com/download?zabbix=5.0&os_distribution=red_hat_enterprise_linux&os_version=8&db=mysql
5.2: https://www.zabbix.com/download?zabbix=5.2&os_distribution=red_hat_enterprise_linux&os_version=8&db=mysql

This commit should make all versions since 3.0 work (this includes all
supported versions.)

Even older (unsupported) versions had additional locations, but this
commit does not include support for those versions. For example, Zabbix
2.0 had scripts in a further subdirectory at
/usr/share/doc/zabbix-server-mysql-2.4.0/create
(https://www.zabbix.com/documentation/2.4/manual/installation/install_from_packages#creating_initial_database)
with three separate scripts; this would break assumptions made elsewhere
in this module.
