Catch errors reading from invalid symbol table file
Catch errors reading from invalid symbol table file

If an invalidly formatted symbol table file was handed to uniprof (e.g.,
because inadvertantly passing the ELF binary file), uniprof might crash
from improperly handling the unexpected input. This catches errors
during the symbol table building phase and disables symbol table
resolution if an error was encountered.
