No error message on incorrectly formatting bpftrace code

[pranav-bhatt]

Describe the bug Upon running my pixie script, after the "preparing schema" step had completed, I had no outputs error messages appear on the UI.

This seemed to be the case when my bpftrace program had incorrect formatting (multiple print statement, presence of '\n', not escaping quotes, etc).

To Reproduce Steps to reproduce the behavior: Run the sample bpftrace script here, but modify the program to have incorrect formatting in the bpftrace code.

Expected behavior A formatting error is spit out when such errors are encountered.
