tools/libressl: update to 4.0.0

Stable version. Odd versions are betas.

Added static patch to rename some ecdsa symbols that conflict with
u-boot's mkimage.

These symbols are not exported by default but because OpenWrt uses a
static libressl, they are present and conflict with mkimage's libecdsa.
