s390/vdso: Generate unwind information for C modules

GDB fails to unwind vDSO functions with error message "PC not saved",
for instance when stepping through gettimeofday().

Add -fasynchronous-unwind-tables to CFLAGS to generate .eh_frame
DWARF unwind information for the vDSO C modules.

Fixes: 4bff8cb54502 ("s390: convert to GENERIC_VDSO")
