fix: correct machine, config, and C library references (verified by build test)

Browse Source 
Critical corrections based on actual build test on 2026-03-01:

1. Machine: tqma6ulx-mba6ulx → tqma6ul-multi-mba6ulx
   (the -multi variant is the correct one for the MBa6ULx carrier)

2. Config: imx → mainline
   (TQMa6UL machines are NOT in the imx config, only in mainline)

3. Carrier: MBa6x → MBa6ULx
   (MBa6x is for the Quad/Dual, MBa6ULx is for the UltraLite)

4. C library: glibc 2.38 → musl 1.2+
   (BSP uses musl: TARGET_SYS=arm-tq-linux-musleabi)

5. README rewritten with verified build output

Verified: DISTRO=spaetzle 5.0.11, BB_VERSION=2.8.0
