apache2: fix service start fail

reproduce steps:
1. boot up target
2. scp apache2-2.4.41-r0.1.aarch64.rpm on target
3. rpm -i apache2-2.4.41-r0.1.aarch64.rpm
4. systemctl status apache2

Error:
httpd[7767]: (2)No such file or directory: AH02291: Cannot access directory '/var/log/apache2/' for main error log

with the old way, /var/log/apache2/ is created by service
systemd-tmpfiles-setup during boot, so only works when apache2
already installed before boot, in above scenario,
/var/log/apache2/ will not created. fix by creating it in the
service file. similar fix for sysV system
