yara doesn't compile if with-debug-verbose flag is enabled

[CatyGreen]

If I run make after ./configure --with-debug-verbose=2 I get the following error:

  CC       proc/linux.lo
In file included from proc/linux.c:42:proc/linux.c: 
In function 'yr_process_get_next_memory_block':
proc/linux.c:408:7: error: 'result' undeclared (first use in this function)
  408 |       result, 

To fix this, I had to add the following line
const uint8_t* result = NULL;
in the function yr_process_get_next_memory_block in libyara/proc/linux.c

Versions affected: yara 4.2.0 and yara 4.2.1

This is odd because I've used that flag a number of times since it was introduced with no problems.

Fixed in 6c5fd5e.

I think that you should change the format too, now there is a warning:
proc/linux.c:407:7: warning: format '%p' expects argument of type 'void *', but argument 4 has type 'YR_MEMORY_BLOCK'
