[PATCH RESEND] xfsprogs: scrub: fix warnings/errors due to missing include

[Holger Hoffstätte]

Gentoo is currently trying to rebuild the world with clang-16, uncovering exciting
new errors in many packages since several warnings have been turned into errors,
among them missing prototypes, as documented at:
https://discourse.llvm.org/t/clang-16-notice-of-potentially-breaking-changes/65562

xfsprogs came up, with details at https://bugs.gentoo.org/875050.

The problem was easy to find: a missing include for the u_init/u_cleanup
prototypes. The error:

Building scrub
     [CC]     unicrash.o
unicrash.c:746:2: error: call to undeclared function 'u_init'; ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
         u_init(&uerr);
         ^
unicrash.c:746:2: note: did you mean 'u_digit'?
/usr/include/unicode/uchar.h:4073:1: note: 'u_digit' declared here
u_digit(UChar32 ch, int8_t radix);
^
unicrash.c:754:2: error: call to undeclared function 'u_cleanup'; ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
         u_cleanup();
         ^
2 errors generated.

The complaint is valid and the fix is easy enough: just add the missing include.
