xsm: fix printf format string for strlen result

strlen returns size_t:

policydb.c: In function \91policydb_read\92:
policydb.c:1779: error: format \91%lu\92 expects type \91long unsigned int\92, but argument 3 has type \91size_t\92

This is probably benign on 64-bit x86 but was found by Dharshini on 32-bit Xen
4.2.x. I expect it affects ARM too.
