print.c: show_dive_header() Reserve more space for strings

Increase the size of "buffer" to 160 bytes. This was causing
a problem with the first call to pango_layout_text(), where
for the "bg_BG" locale, not enought space was allocated for the
month name, the translation of "dive" and the other values.
