selftests: cachestat: Fix warning on declaration under label
Fix warning caused from declaration under a case label. The proper way
is to declare variable at the beginning of the function. The warning
came from running clang using LLVM=1; and is as follows:
-test_cachestat.c:260:3: warning: label followed by a declaration is a C23 extension [-Wc23-extensions]
260 | char *map = mmap(NULL, filesize, PROT_READ | PROT_WRITE,
