Patch to source/tdb/tdb.c for compiling on Tru64 UNIX

[samba-technical at thewrittenword.com]

If compiling 2.2.0 from CVS on Tru64 UNIX 4.0D with 'cc -std', it
appears 'readonly' is a reserved word (-std is ANSI + relaxations
whereas -std1 is ANSI). Patch below renames readonly to read_only to
fix this.
