Don't use hardcoded path to the evmc lib

[qezz]

Describe your changes and provide context

The runtime.Caller(0) returns paths to the source code, not picking them up during runtime.

Testing performed to validate your change

The nodes are starting with giga executor enabled, instead of crashing trying to pick up the wrong hardcoded path to the .so file.

panic: failed to load evmone: evmc.Load("/go/src/github.com/sei-protocol/sei/giga/executor/lib/libevmone.0.12.0_linux_amd64.so"): EVMC loading error: /go/src/github.com/sei-protocol/sei/giga/executor/lib/libevmone.0.12.0_linux_amd64.so: cannot open shared object file: No such file or directory

This issue is fixed on main, in that the default executor used is geth and evmone load failure is scilently ignored. A separate PR improves the UX as well as encorporating the improvement kindly submitted by this PR.

Closing and many thanks for pointing this issue out + PR to fix 🙌
