pppd: Remove usage of incorrect constant MAXIFNAMELEN

MAXIFNAMELEN is currently hardcoded to 32, but maximal size of interface
name on Linux is just 15 + nul-term byte. This limit is already provided by
IFNAMSIZ macro defined in net/if.h header file.

So replace MAXIFNAMELEN usage by IFNAMSIZ to not silently truncate
interface name.
