List third party files in cpukit and testsuites

[Gedare Bloom]

Out of the original list, the following are the files that have NOT
been marked as third-party in my proof-of-concept available at
https://git.rtems.org/gedare/rtems.git/log/?h=test-split-3rd-party

Most of the .h files are not included because uninstalled headers
aren't in the spec files. This includes the following headers:
------------------

The RTL is owned by RTEMS now, including:
------------------
cpukit/libdl/rtl-mdreloc-arm.c
cpukit/libdl/rtl-mdreloc-i386.c
cpukit/libdl/rtl-mdreloc-m68k.c
cpukit/libdl/rtl-mdreloc-riscv.c
cpukit/libdl/rtl-mdreloc-sparc.c
cpukit/libdl/fastlz.c
cpukit/libdl/fastlz.h
------------------

These two are RTEMS-owned, authored by Till and Kevin Kirspel
------------------
cpukit/libfs/src/defaults/default_mmap.c
cpukit/score/cpu/nios2/include/rtems/score/nios2-count-zeros.h
------------------

There are several header files related to ISA-specific support that
might be worth identifying as third-party.
------------------
cpukit/score/cpu/i386/include/machine/elf_machdep.h
cpukit/score/cpu/m68k/include/machine/elf_machdep.h
cpukit/score/cpu/mips/include/machine/elf_machdep.h
cpukit/score/cpu/nios2/include/machine/elf_machdep.h
cpukit/score/cpu/sparc/include/machine/elf_machdep.h
cpukit/score/cpu/x86_64/include/machine/elf_machdep.h
cpukit/score/cpu/mips/include/rtems/mips/idtcpu.h
cpukit/score/cpu/mips/include/rtems/mips/iregdef.h
------------------

Some random files:
------------------
cpukit/include/pci/pcireg.h
cpukit/libmisc/mouse/mouse_parser.c
cpukit/libmisc/xz/xz_crc64.c
------------------

And I didn't touch the testsuites:
------------------
testsuites/samples/paranoia/paranoia.c
testsuites/benchmarks/dhrystone/dhry.h
testsuites/benchmarks/dhrystone/dhry_1.c
testsuites/benchmarks/dhrystone/dhry_2.c
testsuites/benchmarks/linpack/linpack-pc.c
testsuites/benchmarks/whetstone/whetstone.c
