testing/firmware-samsung-a51: Move a51 specific blobs to its own directory (MR 5887)

As @grimler stated in MR !5887 (comment) [1], samsung-jackpotlte,
samsung-xcover4lte, and samsung-a30 share the same name for Wi-Fi
proprietary blobs, and packaged in their own specific firmware package.

The problem is these firmware packages put files in the same directory
as `firmware-samsung-a51`: /lib/firmware/postmarketos/mx140/. This opens
up the probability of conflicting blobs when multiple firmware packages
are installed on the system, resulting in wrong blobs used.

To ensure that this firmware is located in its own directory, move
`samsung-a51` blobs into its own subdirectory. This way, `a51` blobs
will stay intact whether multiple firmware packages are installed.
