fix(parse_def): prevent buffer overflow in register name copy

[Reodus]

Buffer Overflow in arch_parse_reg_profile and parse_def

Description:

In the parse_def function, r->name is a buffer that holds the name of a register. However, it is only 32 bytes in size. But in the arch_parse_reg_profile function, there is a buffer tmp which is 128 bytes long and is used to hold parsed tokens from the reg_profile string.

As you see in parse_def, The strcpy function is used to copy the string from tok[1] into r->name and there is no check to ensure that tok[1] will fit into r->name (which is only 32 bytes). To fix this issue, I replaced strcpy with snprintf, which allows you to specify the maximum size of the destination buffer, ensuring that the string is copied safely and that the buffer boundary is respected.
