selftest/package: Add package separated debug symbols hardlink test

Tweak recipe selftest-hardlink
- addition of libexecdir to simulate multiple directories
- add gdb.sh to run gdb from script which is invoked at test time.
- rename `hello' -> `hello1' to workaround name confliction with the one in lmbench

Add test_gdb_hardlink_debug to selftest/package
- run a qemu and invoke gdb.sh to gdb binaries of selftest-hardlink
- check gdb to read symbols from separated debug hardlink file
- check debug symbols works correctly

[Test without commit `package.bbclass: only one hardlink of separated debug info file in each directory']
