nativesdk-rpm: export RPM_ETCCONFIGDIR and MAGIC in environment like RPM_CONFIGDIR

* the paths in wrapper don't work for rpmdeps which is installed in
  ${libdir}/rpm unlike other wrapped bins from ${bindir} these relative
  paths don't work there

* replace environment.d-rpm.sh with here-doc so that we can use
  OE variables

* in the end it might be better to just get rid of the wrappers at
  this point and depend on environment.d to always set right values

* the wrappers were added in:

    nativesdk-rpm: Add wrappers for nativesdk support

    When installing the SDK to a non-default path, running "rpm --showrc" from the
    sdk will produce the following error:
    error: Unable to open /opt/windriver/wrlinux-small/10.17.41/sysroots/x86_64-wrlinuxsdk-linux/usr/lib/rpm/rpmrc for reading: No such file or directory.
    Fix this by adding wrappers that dynamically export the RPM_CONFIGDIR,
    RPM_ETCCONFIGDIR and MAGIC environment variables, pointing to the proper
    sdk locations.

* the rpm.sh in environment.d a bit later:
  commit 5f16fd0bf774314c79572daf4ba7e4a8ae209ba1

    nativesdk-rpm: adjust RPM_CONFIGDIR paths dynamically

    While installing/extracting SDK to a non-default dir(not /opt),
    run rpm failed:
    $ python3 -c "import rpm"
    |error: Unable to open /opt/windriver/wrlinux-graphics/20.31/sysroots/
    x86_64-wrlinuxsdk-linux/usr/lib/rpm/rpmrc for reading: No such file or
    directory.

    This patch adds a flexible way to configure RPM_CONFIGDIR in SDK.
