Harish Sadineni 37fea972a6 rust: remove redundant cargo config file
YOCTO [#15061]
The rust target and linker are getting setting from the sdk environment and
so the config file is not needed. The redundant config file geneartion is removed.

# Uses SDK's CC as linker so linked binaries works out of box.

# binaries (even /bin/sh) in the SDK as they detect a newer glibc from the SDK
# in those paths and we hit symbol errors. We saw particular problems with symbol

# binary which unsets LD_LIBRARY_PATH, which can then call the wrapper script
