testsuite: Update Wconversion testcase check type.

Some compiler target like arm-linux\riscv\power\s390x\xtensa-gcc handle
char as unsigned char, then there are no warnings occur and got FAIL cases.
Just change the type char into explicit signed char to keep the feature
consistency.

gcc/testsuite/ChangeLog:

	* c-c++-common/Wconversion-1.c: Update type.
