[PATCH] Adjust mangling of "arch" value from scanelf output

scanelf may generate output that looks like this:

```
UNKNOWN_TYPE;lib/firmware/ath10k/WCN3990/hw1.0/wlanmdsp.mbn;;  -  ;
EM_ARM;lib/firmware/mediatek/mt8183/scp.img;;  -  ;
...
```

Previously, we removed the first 3 characters of the first field and
stored this as the "arch" in NEEDED.ELF.2. This unintentionally
changes "UNKNOWN_TYPE" to "NOWN_TYPE".

Instead, let's just remove the string "EM_" from the front.
