1.9.5: samurai: building fails on missing fu-efi-struct.h header file

[LinuxUserGD]

Describe the bug
Similar to #6108 , only reproducible with samurai (works with Ninja)

Steps to Reproduce

meson setup --libdir lib --localstatedir /var/lib --prefix /usr --sysconfdir /etc --wrap-mode nodownload --build.pkg-config-path /var/tmp/portage/sys-apps/fwupd-1.9.5/temp/pkgconfig:/var/tmp/portage/sys-apps/fwupd-1.9.5/temp/python3.11/pkgconfig:/usr/share/pkgconfig --pkg-config-path /var/tmp/portage/sys-apps/fwupd-1.9.5/temp/pkgconfig:/var/tmp/portage/sys-apps/fwupd-1.9.5/temp/python3.11/pkgconfig:/usr/share/pkgconfig --native-file /var/tmp/portage/sys-apps/fwupd-1.9.5/temp/meson.x86_64-gentoo-linux-musl.amd64.ini -Db_pch=false -Dwerror=false --buildtype plain --localstatedir /var -Dbuild=all -Dconsolekit=disabled -Dcurl=enabled -Defi_binary=false -Dman=true -Dsupported_build=enabled -Dudevdir=/usr/lib/udev -Dlibarchive=enabled -Dbash_completion=false -Dbluez=disabled -Dcbor=disabled -Delogind=disabled -Dgnutls=disabled -Ddocs=disabled -Dgusb=enabled -Dlzma=enabled -Dintrospection=disabled -Dpolkit=enabled -Dsqlite=enabled -Dsystemd=enabled -Dtests=false -Dtest-full=false -Dplugin_gpio=enabled -Dplugin_intel_me=disabled -Dplugin_dell=disabled -Dplugin_fastboot=disabled -Dplugin_flashrom=disabled -Dplugin_uf2=enabled -Dplugin_logitech_bulkcontroller=disabled -Dplugin_modem_manager=disabled -Dplugin_nvme=disabled -Dplugin_intel_spi=false -Dplugin_synaptics_mst=disabled -Dplugin_synaptics_rmi=disabled -Dplugin_tpm=enabled -Dplugin_uefi_capsule=disabled -Dplugin_uefi_capsule_splash=false -Dplugin_uefi_pk=disabled /var/tmp/portage/sys-apps/fwupd-1.9.5/work/fwupd-1.9.5 /var/tmp/portage/sys-apps/fwupd-1.9.5/work/fwupd-1.9.5-build
meson compile -C /var/tmp/portage/sys-apps/fwupd-1.9.5/work/fwupd-1.9.5-build --jobs 1 --load-average 0 --verbose
/usr/bin/samu -C /var/tmp/portage/sys-apps/fwupd-1.9.5/work/fwupd-1.9.5-build -j 1 -v

Expected behavior
Compilation works

Maybe related to compile job order?

samurai schedules jobs using a stack, so the last scheduled job is the first to execute
