print.c: Attempt a gettext() fix when printing translated "Gas Used"

print_tanks():
It seems the macro call NC_("Amount","Gas Used") generates an entry in the
.po file that then isn't matched at run time, which makes the bg_BG print
have "Gas Used" in english instead of the translated text (which is
already present in other places).

On the other hand if we use N_ here (only mark it), the printed text
is translated correctly.

[Dirk Hohndel: added GETTEXT comment in code and rephrased commit message]
