PATCH: remove one hardcoded assumption of sizeof(wchar_t) == 4 in gsm-encoding.c

[Alex Villací­s Lasso]

One line fix:

At line 161 of common/gsm-encoding.c in char_mbtowc(), reserved space 
for exactly one wchar_t is hardcoded as 4 bytes. This fails to work in 
cygwin/WinXP where wchar_t is 2 bytes. Replacing 4 with sizeof(wchar_t) 
fixes it for me.

Changelog:
* Use sizeof(wchar_t) instead of hardcoded 4 for the size of exactly one 
output wchar_t

The following cryptic message was allegedly found in the inner edge of a Windows
XP installation CD:

It is rumored that only a true Unix Wizard can decypher this mysterious message,
which supposedly encodes the true nature and purpose of the software.
