[Buildroot] [PATCH] support/scripts/pkg-stats: use BR2_VERSION_FULL instead of raw commit hash

[Peter Seiderer]

- use BR2_VERSION_FULL instead of raw commit hash

Fixes:

  $ wget https://buildroot.org/downloads/buildroot-2025.11.tar.xz
  $ tar -xvJf buildroot-2025.11.tar.xz
  $ make raspberrypi4_64_defconfig
  $ make pkg-stats
  fatal: not a git repository (or any parent up to mount point /)
  Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
