scripts/tags.sh: Invoke 'realpath' via 'xargs'
When COMPILED_SOURCE is set, running make ARCH=x86_64 COMPILED_SOURCE=1 cscope tags could throw the following errors: scripts/tags.sh: line 98: /usr/bin/realpath: Argument list too long cscope: no source files found scripts/tags.sh: line 98: /usr/bin/realpath: Argument list too long ctags: No files specified. Try "ctags --help". This is most likely to happen when the kernel is configured to build a large number of modules, which has the consequence of passing too many arguments when calling 'realpath' in 'all_compiled_sources()'. Let's improve this by invoking 'realpath' through 'xargs', which takes care of properly limiting the argument list.
