[build]: marvell-armhf bullseye fixes (#9243)

This commit fixes/avoids the following errors encountered during the
marvell-armhf build for bullseye

- Fix Marvell prestera DMA driver build failure due to kallsyms_lookup_name()
  no longer being exported by the updated bullseye kernel. This is a temporary
  fix that will be replaced by a future version of the DMA driver.

- Update qemu-user-static version to align with the new glibc version included
  in bullseye

- Skip systemd-sonic-generator unit tests to avoid test failures. Root cause is
  still TBD

#### Why I did it
Fix the following build errors observed when building marvell-armhf for bullseye
1. Marvell Prestera DMA driver uses kernel API no longer exported
ERROR: modpost: "kallsyms_lookup_name" [/sonic/platform/marvell-armhf/prestera/mrvl-prestera/cpssEnabler/linuxNoKernelModule/drivers//mvDmaDrv.ko] undefined!

2. Old qemu-user-static version does not support semop() leading to following build failure
semop(1): encountered an error: Function not implemented

3. systemd-sonic-generator unit test failure
ssg-test.cc:217: Failure
Expected equality of these values:
  find_string_in_file(str_t, target, num_asics)
    Which is: false
  expected_result
    Which is: true
