Fixes errors being ignored

I found that amd64 build is currently failing because of:

+ go build -ldflags -s -w -trimpath -o go2rtc_linux_amd64
package github.com/AlexxIT/go2rtc
        imports github.com/AlexxIT/go2rtc/internal/v4l2
        imports github.com/AlexxIT/go2rtc/pkg/v4l2/device: C source files not allowed when not using cgo or SWIG: videodev2_arch.c

Which was being ignored previously and then this architecture would not be built.

Display commands being executed

With set -x so that it's easier to follow the script's progress.

@AlexxIT I would also suggest removing build.cmd as you can run build.sh on Windows using Git Bash.

[AlexxIT]

I can't run it from GoLand console. I think other Windows users won't be able to handle the shell file either.

.\scripts\build.sh
Program 'build.sh' failed to run: No application is associated with the specified file for this operationAt line:1 char:1

@skrashevich what do you this about this changes? I'm not a big expert on shell files.

[skrashevich]

Good changes. There are no issues with the script on *nix systems. On Windows, it must be run through Bash

[felipecrs]

@AlexxIT can you try bash .\scripts\build.sh?

Otherwise maybe you don't have Git Bash installed (it comes with Git for Windows).

But anyway, I am not deleting the cmd script.
