Bug #102384 InnoDB initialization failed on EXT3 filesystem

Description:
WL#13782 in MySQL 8.0.22 introduced a bug which causing InnoDB initialization
failed on EXT3 filesystem.

Just like https://bugs.mysql.com/bug.php?id=74167, EXT3 filesystem doesn't
support posix_fallocate, and it will return EINVAL(https://man7.org/linux/man-pages/man3/posix_fallocate.3.html).

How to repeat:
Initialize mysql server on EXT3 filesystem.
And it'll report error like:

2021-01-22T17:58:00.416838+08:00 1 [ERROR] [MY-012128] [InnoDB] posix_fallocate(): Failed to preallocate data for file ./#innodb_temp/temp_1.ibt, desired size 81920 Operating system error number 22. Check that the disk is not full or a disk quota exceeded. Make sure the file system supports this function. Refer to your operating system documentation for operating system error code information.
2021-01-22T17:58:00.417461+08:00 1 [ERROR] [MY-012929] [InnoDB] InnoDB Database creation was aborted with error Out of disk space. You may need to delete the ibdata1 file before trying to start up again.

2021-01-22T17:58:00.906908+08:00 0 [System] [MY-010910] 

Suggested fix:

The fix can be ignore this error for temp table and take plan B which will call os_file_set_size.
