Fix an issue for make dist: once the internal/resources directory contains no files, //go:embed will be invalid

[TianyouLi]

Problem

When build as 'make dist', it will report errors like below:

   internal/script/script.go:21:3: invalid go:embed: build system did not supply embed configuration (compile)
   internal/script/script.go:21:12: pattern resources: cannot embed directory resources: contains no embeddable files (compile)
   make: *** [Makefile:90: check_static] Error 1

Proposed Solution

Check if the resources/x64 directory is empty, if yes, just touch a empty file to workaround the go compilation error

Prefer that build fails when binaries are not present. The binaries are required for perfspect to operate properly.
