-Werror,-Wdeprecated-declarations (sprintf, macOS 13 SDK): soltools

These occurrences of sprintf in C code don't normally trigger the deprecation
warning at least with recent macOS, because macOS by default now enables
_FORTIFY_SOURCE (see the code setting it in
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.0.sdk/usr/include/_types.h
when originally unset), which for C code hides the declaration of sprintf (along
with its deprecation annotation) in
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.0.sdk/usr/include/stdio.h
with a macro (expanding to __builtin___sprintf_chk) in
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.0.sdk/usr/include/secure/_stdio.h.
But they started to trigger when I did an experimental -fsanitize=address build,
because
<https://github.com/llvm/llvm-project/commit/b4f819086a61b5a843f0171a7467c5184ba1b086>
"Disable source fortification on Darwin with AddressSanitizer" predefines
-D_FORTIFY_SOURCE=0 in that case.

While there might be ways to clean this code up to use something better than the
deprecated sprintf, don't bother too much with this 3rd-party, build-time--only
code and just silence any potential deprecation warnings.
