[ptxdist] [PATCH] kernel: Call chmod modules.builtin.modinfo for v6.x only

[Alexander Dahl via ptxdist <ptxdist@pengutronix.de>]

kernel.install stage fails for kernel versions before v5.2 (which
introduced modules.builtin.modinfo in the first place) like this:

      DEPMOD  4.9.327-rt197-tt
    depmod: WARNING: could not open modules.builtin.modinfo at [redacted]/platform-ncl/packages/linux-4.9.327/lib/modules/4.9.327-rt197-tt: No such file or directory
    chmod: cannot access '[redacted]/platform-ncl/packages/linux-4.9.327/lib/modules/*/modules.builtin.modinfo': No such file or directory
    make: *** [/usr/local/lib/ptxdist-2026.01.0/rules/kernel.make:287: [redacted]/platform-ncl/state/kernel.install] Error 1
    ptxdist install kernel  3,75s user 1,63s system 101% cpu 5,308 total

The chmod fix is only necessary for kernel v6.18 which introduced the
faulty executable permissions.  It was fixed for v6.19 with kernel commit
6d60354ea2f9 ("kbuild: Fix permissions of modules.builtin.modinfo").
