Ilya Leoshkevich 16da961911 linux-user: Fix strace output for s390x mmap() ...

print_mmap() assumes that mmap() receives arguments via memory if
mmap2() is present. s390x (as opposed to s390) does not fit this
pattern: it does not have mmap2(), but mmap() still receives arguments
via memory.

Fix by sharing the detection logic between syscall.c and strace.c.
