KVM: selftests: Make TEST_ASSERT_EQ() output look like normal TEST_ASSERT()

Browse Source 
Clean up TEST_ASSERT_EQ() so that the (mostly) raw code is captured in the
main assert message, not the helper macro's code.  E.g. make this:

  x86_64/tsc_msrs_test.c:106: __a == __b
  pid=40470 tid=40470 errno=0 - Success
     1	0x000000000040170e: main at tsc_msrs_test.c:106
     2	0x0000000000416f23: __libc_start_call_main at libc-start.o:?
     3	0x000000000041856f: __libc_start_main_impl at ??:?
     4	0x0000000000401ef0: _start at ??:?
  TEST_ASSERT_EQ(rounded_host_rdmsr(MSR_IA32_TSC), val + 1) failed.
	rounded_host_rdmsr(MSR_IA32_TSC) is 0
	val + 1 is 0x1

look like this:

  x86_64/tsc_msrs_test.c:106: rounded_host_rdmsr(MSR_IA32_TSC) == val + 1
  pid=5737 tid=5737 errno=0 - Success
     1	0x0000000000401714: main at tsc_msrs_test.c:106
     2	0x0000000000415c23: __libc_start_call_main at libc-start.o:?
     3	0x000000000041726f: __libc_start_main_impl at ??:?
     4	0x0000000000401e60: _start at ??:?
  0 != 0x1 (rounded_host_rdmsr(MSR_IA32_TSC) != val + 1)

Opportunstically clean up the formatting of the entire macro.
