rfs.c: fix integer comparison sign with variable

With:
    ./configure CC=clang CFLAGS=-W -Wall -Wno-unused \
                --no-create --no-recursion
we have:
    rfs.c:86:20: warning: comparison of integers of
    different signs: '__off_t' (aka 'long') and 'size_t'
    (aka 'unsigned int') [-Wsign-compare]
    if (st.st_size != size) {
        ~~~~~~~~~~ ^  ~~~~
    rfs.c:146:20: warning: comparison of integers of
    different signs: '__off_t' (aka 'long') and 'size_t'
    (aka 'unsigned int') [-Wsign-compare]
    if (st.st_size != size) {
        ~~~~~~~~~~ ^  ~~~~

This is caused by the following code:
    size_t size;
    [...]
    rc = stat([...], &st);
    if (st.st_size != size) {
      [...]
    }

However the type of size is wrong as the stat system call
returns a stat structure which has the following field:
    off_t     st_size;        /* Total size, in bytes */
