What changes were proposed in this pull request?

Fix the error message emitted by ozone when built without -Pdist:

$ cd hadoop-ozone/dist/target/ozone-2.3.0-SNAPSHOT

$ bin/ozone debug checknative    
bin/../libexec/ozone-functions.sh: line 1384: cd: lib/native: No such file or directory
Native library checking:
     hadoop:  false  
...

$ ls lib/native
ls: cannot access 'lib/native': No such file or directory

Also when built with -Pdist, but not executed from OZONE_HOME directory:

$ cd hadoop-ozone/dist/target/ozone-2.3.0-SNAPSHOT/bin
$ ./ozone debug checknative
bin/../libexec/ozone-functions.sh: line 1384: cd: lib/native: No such file or directory
Native library checking:
     hadoop:  true   lib/native/libhadoop_linux_x86_64.so

Reduce code duplication between Linux and Mac-specific branches.

How was this patch tested?

Without -Pdist:

$ mvn -DskipRecon -DskipShade -DskipTests clean verify
...
$ cd hadoop-ozone/dist/target/ozone-2.3.0-SNAPSHOT
$ ls lib/native
ls: cannot access 'lib/native': No such file or directory

$ bin/ozone debug checknative
Native library checking:
     hadoop:  false
...

With -Pdist:

$ mvn -DskipRecon -DskipShade -DskipTests clean verify -Pdist
...
$ cd hadoop-ozone/dist/target/ozone-2.3.0-SNAPSHOT
$ bin/ozone debug checknative
Native library checking:
     hadoop:  true   lib/native/libhadoop_linux_x86_64.so
...

$ ls -1 --file-type lib/native
libhadoop.dylib@
libhadoop_linux_aarch_64.so
libhadoop_linux_x86_64.so
libhadoop_osx_aarch_64.dylib
libhadoop.so@

$ cd bin
$ ./ozone debug checknative
Native library checking:
     hadoop:  true   lib/native/libhadoop_linux_x86_64.so
...
