[PATCH 3/3] libsepol: fix unitialized variable 'nread' on mac build

[william.c.roberts@xxxxxxxxx]

From: William Roberts <william.c.roberts@xxxxxxxxx>

Fix this:
genusers.c:63:14: warning: variable 'nread' is uninitialized when used here [-Wuninitialized]
                if (buffer[nread - 1] == '\n')
                           ^~~~~
genusers.c:40:15: note: initialize the variable 'nread' to silence this warning
        ssize_t nread;
                     ^
                      = 0
