libgd: fix unitialized warnings during make check (fixes #65)

gifanimtest.c: In function 'main':
gifanimtest.c:7: warning: unused parameter 'argc'
gifanimtest.c:7: warning: unused parameter 'argv'

gd_color_map_test.c: In function 'main':
gd_color_map_test.c:10: warning: unused parameter 'argc'
gd_color_map_test.c:10: warning: unused parameter 'argv'

circletexttest.c: In function 'main':
circletexttest.c:8: warning: unused parameter 'argc'
circletexttest.c:8: warning: unused parameter 'argv'

fontsizetest.c: In function 'main':
fontsizetest.c:79: warning: unused parameter 'argc'
fontsizetest.c:79: warning: unused parameter 'argv'

fontwheeltest.c: In function 'main':
fontwheeltest.c:116: warning: unused parameter 'argc'
fontwheeltest.c:116: warning: unused parameter 'argv'

testtr.c: In function 'main':
testtr.c:12: warning: unused parameter 'argc'
testtr.c:12: warning: unused parameter 'argv'

Only one unused variable 'in' remain because I am lazy to add  __attribute__((unused)) when supported.
