crypto/scheduler: fix include of local headers

When a C file for a library/driver is including the public header files for
that library, those need to be included as local includes using quotes
rather than angle-brackets. Without doing so, parallel builds can fail, as
the compiler will only look for those headers in the global include folder
rather than locally, and the build system does not enforce that the headers
for a lib are installed before the rest of the lib is compiled.
