UBUNTU: SAUCE: split failed tests out

BugLink: https://bugs.launchpad.net/bugs/1938875

vmx test contain a bunch of different tests.
Split failed test cases in vmx out as standalone tests to improve our
test granularity. Make it easier to do result hinting and allow this
test to finish properly without being terminated prematurely.

This SAUCE patch will split the following tests out of vmx:
  * rdtsc_vmexit_diff_test
  * test_vmread_flags_touch
  * test_vmwrite_flags_touch
  * test_vmwrite_vmread
  * test_vmxon
  * vmx_apic_passthrough_test
  * vmx_controls_test
  * vmx_cr_load_test
  * vmx_cr4_osxsave_test
  * vmx_db_test
  * vmx_guest_state_area_test
  * vmx_hlt_with_rvi_test
  * vmx_host_state_area_test
  * vmx_intr_window_test
  * vmx_mtf_test
  * vmx_mtf_pdpte_test
  * vmx_nmi_window_test
  * vmx_pending_event_test
  * vmx_preemption_timer_tf_test
  * vmx_preemption_timer_zero_test
  * vmx_store_tsc_test

arm64: Fix sve_vl() for build errors

commit 5b9895f8a5d9 ("arm: Fix clang error in sve_vl()") breaks the build
with the following compiler version, as the "rdvl" expects a 64bit register.

/tmp/ccGJYtuC.s: Assembler messages:
/tmp/ccGJYtuC.s:2165: Error: operand mismatch -- `rdvl w3,#8'
/tmp/ccGJYtuC.s:2165: Info: did you mean this?
/tmp/ccGJYtuC.s:2165: Info: rdvl x3, #8
make: *** [<builtin>: arm/selftest.o] Error 1
make: *** Waiting for unfinished jobs....

$ aarch64-none-elf-gcc --version
aarch64-none-elf-gcc (GNU Toolchain for the A-profile Architecture 10.2-2020.11 (arm-10.16)) 10.2.1 20201103

Fix this by switching to use "unsigned long" variable and restoring the 64bit
register for the instruction

pretty_print_stacks: modify relative path calculation

Don't assume we can get a relative path by cutting of certain prefixes,
since this isn't guaranteed to work.
Instead use a library function.
Also normalize paths in order to take care of symlinks.

UBUNTU: SAUCE: Revert "s390x: add test for SIGP STORE_ADTL_STATUS order"

The ADTL test will fail to build on Xenial with:
    s390x/adtl-status.c:204:1: error: unrecognizable insn:

Since this is already an EOL series, let just revert these adtl tests.

This reverts commit db1f35d9375bb7a3854dd8a7a18536b0ec372b16.
