Builds with --dynamic-libengines are currently broken, because the rule
to build the libraries was moved out of the template that creates them:
make: *** No rule to make target 'engines/libpmem.so', needed by 'all'. Stop.
make: *** Waiting for unfinished jobs....
Fix this by moving the rule back into the template, calling the template
to create rules only after FIO_CFLAGS has been incorporated into CFLAGS,
and using CFLAGS + -fPIC in that rule rather than FIO_CFLAGS.
Fixes: 8a2cf08d29ac ("Makefile: introduce FIO_CFLAGS")
