[v2,1/1] devtools: add relative path support for ABI compatibility check

  From: Phil Yang <phil.yang@arm.com>

Because dpdk guide does not limit the relative path for ABI
compatibility check, users maybe set 'DPDK_ABI_REF_DIR' as a relative
path:

~/dpdk/devtools$ DPDK_ABI_REF_VERSION=v19.11 DPDK_ABI_REF_DIR=build-gcc-shared
./test-meson-builds.sh

And if the DESTDIR is not an absolute path, ninja complains:
+ install_target build-gcc-shared/v19.11/build build-gcc-shared/v19.11/build-gcc-shared
+ rm -rf build-gcc-shared/v19.11/build-gcc-shared
+ echo 'DESTDIR=build-gcc-shared/v19.11/build-gcc-shared ninja -C build-gcc-shared/v19.11/build install'
+ DESTDIR=build-gcc-shared/v19.11/build-gcc-shared
+ ninja -C build-gcc-shared/v19.11/build install
...
ValueError: dst_dir must be absolute, got build-gcc-shared/v19.11/build-gcc-shared/usr/local/share/dpdk/
examples/bbdev_app
...
Error: install directory 'build-gcc-shared/v19.11/build-gcc-shared' does not exist.

To fix this, add relative path support using 'readlink -f'.
