[PATCH:setxkbmap 2/3] Make len a size_t instead of converting back & forth to an int

[Alan Coopersmith]

Gets rid of a number of clang warnings:
setxkbmap.c:689:28: warning: implicit conversion loses integer precision:
    'unsigned long' to 'int' [-Wshorten-64-to-32]
        len = strlen(orig) + 1;
            ~ ~~~~~~~~~~~~~^~~
setxkbmap.c:701:39: warning: implicit conversion changes signedness:
    'int' to 'size_t' (aka 'unsigned long') [-Wsign-conversion]
        orig = (char *) realloc(orig, len);
                        ~~~~~~~       ^~~
setxkbmap.c:707:32: warning: implicit conversion changes signedness:
    'int' to 'size_t' (aka 'unsigned long') [-Wsign-conversion]
        orig = (char *) calloc(len, 1);
                        ~~~~~~ ^~~
