Remove old libc elf auxillary vector check
In some old 32-bit libc's, it was cheaper for the loader to put the
value of the kernel's system call entry point (AT_SYSINFO) into a fixed
location. One particular place was at 'gs:0x10'. That value was likely
taken from https://articles.manugarg.com/systemcallinlinux2_6.html. In
this case, 'call gx:0x10' iss really a system call.
However, the check implemented here would never work for two reasons.
First, Dyninst doesn't generate AST for the segment registers, so
'isRead(gs)' would always be false. Second, the Operand formatter uses
AT&T syntax and doesn't convert hex to decimal, so the '== "16"' check
always failed, as well.
Given this incorrect check and that the 0x10 offset wasn't guaranteed, I
think we should just remove it.
