Rollup merge of #131774 - thesummer:rtems-add-getentropy, r=joboet
Add getentropy for RTEMS RTEMS provides the `getentropy` function. Use this for providing random data. This PR enables the `getentropy` function for the RTEMS operating system to get random data. It is exposed via libc (see https://github.com/rust-lang/libc/pull/3975).
