osasnmpd: Add -fPIC to CFLAGS to fix build on Fedora 27

Browse Source 
On Fedora 27 "net-snmp-config --agent-libs" returns
"--specs=/usr/lib/rpm/redhat/redhat-hardened-ld" which introduces "-pie":

 # cat /usr/lib/rpm/redhat/redhat-hardened-ld
 *self_spec:
 + %{!static:%{!shared:%{!r:-pie}}}
 *link:
 + -z now

This leads to the following link error:

 /usr/bin/ld: osasnmpd.o: `getopt_long@@GLIBC_2.2' non-PLT reloc for symbol
              defined in shared library and accessed from executable
              (rebuild file with -fPIC ?)
 /usr/bin/ld: final link failed: Bad value

Add -fPIC to CLFAGS as a workaround to enbable linking again.
