-----------
Remove explicit check for system calls in parse_frame_one_iteration
165f19cd and 091929d6 changed the parsing semantics of system calls
such that software interrupts (e.g., `int` on x86) are always
interpreted as system calls. The `hasCFT()` check on line 1824 now
covers all of the system call cases because it considers those
instructions to have a control flow target (CFT).
Its non-use was verified against /usr/libx32/libc.so.6,
/usr/lib/i386-linux-gnu/libc.so.6, /usr/lib/x86_64-linux-gnu/libc.so.6,
and /usr/lib32/libc.so.6 on Ubuntu 22.04.
