[OE-core] [PATCH][master][dizzy][daisy] utils.bbclass: fix create_cmdline_wrapper

[Javier Viguera]

Similar to commit 4569d74 for create_wrapper function, this commit fixes
hardcoded absolute build paths in create_cmdline_wrapper.

Otherwise we end up with incorrect paths in users of this function. For
example the 'file' wrapper in current released toolchain:

exec -a
/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-fsl-arm/build/build/tmp/work/x86_64-nativesdk-pokysdk-linux/nativesdk-file/5.18-r0/image//opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/bin/file
`dirname $realpath`/file.real --magic-file
/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/share/misc/magic.mgc
"$@"
