leaking_addresses: skip '/proc/1/syscall'

The pointers listed in /proc/1/syscall are user pointers, and negative
syscall args will show up like kernel addresses.

For example

/proc/31808/syscall: 0 0x3 0x55b107a38180 0x2000 0xffffffffffffffb0 \
0x55b107a302d0 0x55b107a38180 0x7fffa313b8e8 0x7ff098560d11
