minicoredumper: backport patch to build with glibc 2.43

As the subject says.

Fixes compilation error:
| ../../../sources/minicoredumper-2.0.7/src/coreinject/main.c: In function 'inject_data':
| ../../../sources/minicoredumper-2.0.7/src/coreinject/main.c:248:11: error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
|   248 |         p = strrchr(b_fname, '/');

+Subject: [PATCH] coreinject: fix assignment of const-qualified type
+
+coreinject fails to build with glibc 2.43.
+
+The issue is due to a new glibc feature:
+
+* For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr,
+  strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return
+  pointers into their input arrays now have definitions as macros that
+  return a pointer to a const-qualified type when the input argument is
+  a pointer to a const-qualified type.
+
+The fix is trivial since the returned strrchr() value is only used in
+a way compatible with const pointers. The data type was simply defined
+incorrectly.
