Minor installation bug

[Pablo Halpern]

The STL portion of the egcs C++ header files support the new #include naming
convention whereby standard headers don't end in ".h".  However, the
iostream-related files only appear with the .h names.  The following files
that were absent:

fstream
iomanip
istream
ostream
streambuf

Each of these was easily created by creating a one-line file that #includes
the old-fashoned name (which should remain for backwards-compatability).  In
other words, file fstream should contain the single line:

#include <fstream.h>
