tests: fix "comparison between signed and unsigned" compilation warnings

preadv-pwritev.c: In function 'main':
preadv-pwritev.c:162: warning: comparison between signed and unsigned
readv.c: In function 'main':
readv.c:148: warning: comparison between signed and unsigned
recvmsg.c: In function 'main':
recvmsg.c:148: warning: comparison between signed and unsigned

* tests/preadv-pwritev.c (main): Cast r_len to int.
* tests/readv.c (main): Likewise.
* tests/recvmsg.c (main): Likewise.
