redefinition of errno in some syscalls tests

I found that some of the testcases in kernel/syscalls redefine 'errno' as 'int':

int errno;

'errno' is normally in errno.h as a #define to a function returning a pointer, i.e.,

extern int *__errno_location (void) . . .

Attached is a patch to remove the redefinition from the following files:

testcases/kernel/syscalls/mallopt/mallopt01.c
testcases/kernel/syscalls/memcmp/memcmp01.c
testcases/kernel/syscalls/memcpy/memcpy01.c
testcases/kernel/syscalls/memset/memset01.c
testcases/kernel/syscalls/syscall/syscall01.c
testcases/kernel/syscalls/string/string01.c
