[testsuite, c++] Use signed char in g++.dg/template/char1.C

[Rainer Orth]

The g++.dg/template/char1.C test FAILs on mips-sgi-irix6.5 on mainline:

FAIL: g++.dg/template/char1.C  (test for warnings, line 4)

This happens because the test assumes that char is signed, but on IRIX,
it is unsigned.  Fixed thus, tested with the appropriate runtest
invocations on mips-sgi-irix6.5 and i386-pc-solaris2.11.

Ok for mainline, though I suppose this is obvious.

Thanks.
