[Bug 1949652] [NEW] Improve performance by changing the block size to 8M

[Yao Wei]

Public bug reported:

This issue is found in usb-creator 0.3.11 in impish.

I found that creating USB disks in GNOME Disks is 2x faster than Startup
Disk Creator, and here's the comparison:

Startup Disk Creator: 1:52
GNOME Disks: 0:37
With a Sandisk Extreme Pro USB drive (CZ880) and a 4.0G image

After I changed the default block_size from 1000000 to 8388608 in
USBCreator._builtin_dd function in the Python file /usr/share/usb-
creator/usb-creator-helper, this can improve the writing speed and
making it about 0:30 to write the same disk image.
