When using "skip" mode, be able to check "No such file".
Currently, logs will be skipped when creating file.

Steps to reproduce:
1. Create a new log item key (No file with skip mode)

- log[/tmp/logtest.log,,,,skip,]

Zabbix logs occurred in 2 minutes active check

active check "log[/tmp/logtest.log,,,,skip,]" is not supported: Cannot obtain information for file "/tmp/logtest.log": [2] No such file or directory

2. Create a new file for monitoring

echo Error_1 > /tmp/logtest.log / Create a new log
echo Error_2 >> /tmp/logtest.log
echo Error_3 >> /tmp/logtest.log

"No such file" error disappears. but error_1~3 does not contained history data (skipped)

3. Remove "/tmp/logtest.log" file.
"No such file" error will start showing again.

4. Recreate a new file "/tmp/logtest.log"

echo Error_4 > /tmp/logtest.log?/ Create a new file
echo Error_5 >> /tmp/logtest.log
echo Error_6 >> /tmp/logtest.log

Start collecting logs from here.
