linux-user/syscall.c: fix missed flag for shared memory in open_self_maps
The possible variants for region type in /proc/self/maps are either
private "p" or shared "s". In the current implementation,
we mark shared regions as "-". It could break memory mapping parsers
such as included into ASan/HWASan sanitizers.
Fixes: 01ef6b9e4e4e ("linux-user: factor out reading of /proc/self/maps")
