With gcc 14, I get this warning/werror when building the localedata tests:
tests-mbwc/tsp_common.c: In function ‘result.constprop.isra’:
tests-mbwc/tsp_common.c:55:43: error: ‘%s’ directive writing up to 92 bytes into a region of size between 0 and 114 [-Werror=format-overflow=]

cc1: all warnings being treated as errors
This patch now gets rid of using sprintf and the result_rec buffer and just
prints to fp directly.
