Fix a build warning in scripts/mod/file2alias.c

On some systems, __used is already defined in sys/cdefs.h and causes
a build warning:

scripts/mod/file2alias.c:85:1: warning: "__used" redefined
In file included from /usr/include/stdio.h:64,
                 from scripts/mod/modpost.h:1,
		                  from scripts/mod/file2alias.c:13:
				  /usr/include/sys/cdefs.h:146:1: warning: this is the location of the previous definition

This adds an extra check before defining the __used macro to see if
the macro was already defined elsewhere.
