lsb: Change link of ${baselib} to lib64 for 64bits system

Correct two faults:

1 Binaries of lsb test suite need ld-linux.so* in /lib64.
for example:
Target$ ./lsbcmdchk
-sh: ./lsbcmdchk: No such file or directory
Target$ strings lsbcmdchk | grep "ld-"
/lib64/ld-lsb-x86-64.so.3

"lsbcmdchk" from lsb test suite is a binary program.
A new modification to lsb_1.4.bb caused that binaries from lsb test suite can't run
because binaries of lsb test suite need ld-linux.so* in /lib64.
But the link is changed due to adding multilib. I changed this link again.

2 correct mandir
Waring will appear when running task task do_populate_sysroot

NOTE: package lsb-1.4-r2: task do_populate_sysroot: Succeeded
WARNING: For recipe lsb, the following files were installed but not shipped in any package:
WARNING:   /{datadir}/man/man1/lsb_release.1.gz

I changed mandir=${D}/man to mandir=${D}/${datadir}/man
