gzip-native is only in do_deploy[depends]. On a fresh work directory,
do_compile runs the host gzip to create kernel/config_data.gz and,
with CONFIG_KERNEL_GZIP, the compressed kernel payload.

do_unpack cleans ${B} but not the recipe sysroot. After do_deploy has
run once, a rebuild from do_unpack picks up pigz from gzip-native
instead. Same .config, same uncompressed IKCONFIG data, but
config_data.gz and the kernel image come out different.

Add gzip-native to DEPENDS so the same compressor is used from the
first do_compile, and drop it from do_deploy[depends], which DEPENDS
now covers.

Notes:
    Changes in v2:
    - drop gzip-native from do_deploy[depends], as Bruce suggested. The
      modules tarball in do_deploy still gets pigz: do_deploy reaches
      gzip-native through do_install (checked with bitbake -g, not with
      a build).
    - kept Bruce's Ack, the only change is the one he suggested
    
    v1: https://patchwork.yoctoproject.org/project/oe-core/patch/20261029124742.3223868-1-vinicius.eduardo.pedrosa@gmail.com/
