ELF+DWARF: always parse first entry in source file table (#1184)

rocm-4.5 starts to emit AMD GPU binaries with DWARF 5. I noticed missing source line information for these binaries. The root cause is that dyninst assumes that source file table entry 0 represents "unknown file". This no longer seems to be true in DWARF 5, where entry 0 can represents a real application source file.
