Subject: [PATCH] zbarcam/zbar{cam,img}.c: fix build with musl

setlocale is used since version 0.23.1 and
https://git.linuxtv.org/zbar.git/commit/id=d05911f8d5fb8c1e064bd93ed9ec9f038c5da096

Include locale.h to avoid the following build failure on musl:

zbarcam/zbarcam.c:168:5: warning: implicit declaration of function 'setlocale'; did you mean 'setstate'? [-Wimplicit-function-declaration]
     setlocale (LC_ALL, "");
     ^~~~~~~~~
     setstate
zbarcam/zbarcam.c:168:16: error: 'LC_ALL' undeclared (first use in this function)
     setlocale (LC_ALL, "");
                ^~~~~~

Fixes:
