Fix timeout_interval declarations

There are different declarations for timeout_interval:

lib/utils_base.c has the definition:
	unsigned int timeout_interval = DEFAULT_SOCKET_TIMEOUT;
lib/utils_base.h has the appropiate declaration:
	extern unsigned int timeout_interval;

plugins/popen.h has an extra declaration:
	extern unsigned int timeout_interval;
This doesn't hurt, but it's a dupe. The one in utils_base.h
should be enough, so remove this one.

plugins/popen.c has a WRONG one:
	extern int timeout_interval;
Remove it!
Use #include "utils.h" to get the right one.
This makes the local defines for max/min unnecassary, so
remove them also.
