Don't include bsd/string.h if strlcpy is also defined in string.h to
avoid the following build failure on uclibc:
In file included from src/compat.hpp:41:0,
from src/ipc_address.cpp:31:
/tmp/instance-0/output-1/host/mips64el-buildroot-linux-uclibc/sysroot/usr/include/bsd/string.h:44:54: error: declaration of 'size_t strlcpy(char*, const char*, size_t)' has a different exception specifier
size_t strlcpy(char *dst, const char *src, size_t siz);
^
