link against libomp on OPENMP=on

after07fb2d5e9d00 and 54cc4cc6eaed14e3d495ca3a3b6f86f3f429b991 , shotwell fails
on libraw if libraw is built with OPENMP=on:
  ld-elf.so.1: /usr/local/lib/libraw.so.20: Undefined symbol "__kmpc_fork_call"
(this can be observed on any operation on RAW files - viewing preprocessed
files or importing JPEGs seems to be ok in any case).

This can be fixed by adding -lomp to libraw's LDFLAGS (OPENMP_LDFLAGS), as per
the attached patch. "works for me and poudriere" (that bumps libraw's
PORTREVISION). (yes, adding -lomp to shotwell does not help).
