Statically link deskd for chroot deployment

The binary runs inside an OpenBSD httpd chroot with no access to
shared libraries. Add -static to the default link flags via a
LDFLAGS_STATIC variable that can be overridden (e.g. LDFLAGS_STATIC=
on macOS where static linking is not supported).

SQLite's static library depends on pthread and math, so add -lpthread
and -lm to the link flags.
