elfutils: fix ptest failures

* Add missing files which needed by ptest test
  to fix the ptest failures such as:
  | sh: ../src/elflint: No such file or directory
  | FAIL: asm-tst4

* Rework 0001-skip-the-test-when-gcc-not-deployed.patch
  to skip the tests which depend on gcc

* Define INHIBIT_PACKAGE_STRIP_FILES for elfutils to
  avoid stripping some generated binaries otherwise
  some of the tests such as test-nlist, run-strip-reloc.sh,
  run-strip-strmerge.sh and so on will fail

* Set EXCLUDE_PACKAGES_FROM_SHLIBS = "${PN}-ptest"
  to avoid ${PN}-ptest be the shlibs provider to
  fix below error:
  Problem 1: package rpm-1:4.14.2.1-r0.core2_32 requires elfutils-ptest >= 0.176, but none of the providers can be installed
  - conflicting requests
  - nothing provides elfutils-binutils needed by elfutils-ptest-0.176-r0.core2_32
  Problem 2: package dnf-4.2.2-r0.core2_32 requires python3-rpm, but none of the providers can be installed
  - package python3-rpm-1:4.14.2.1-r0.core2_32 requires elfutils-ptest >= 0.176, but none of the providers can be installed
  - conflicting requests
  - nothing provides elfutils-binutils needed by elfutils-ptest-0.176-r0.core2_32
  Problem 3: package ltp-20190115-r0.core2_32 requires iproute2, but none of the providers can be installed
  - package packagegroup-core-tools-testapps-1.0-r2.qemux86 requires ltp, but none of the providers can be installed
  - package iproute2-5.1.0-r0.core2_32 requires elfutils-ptest >= 0.176, but none of the providers can be installed
  - conflicting requests
  - nothing provides elfutils-binutils needed by elfutils-ptest-0.176-r0.core2_32
