Jan Kratochvil 0375056af0 Fix resolving ELF symbols for live PIDs with deleted files
For deleted shared library files the offsets to the symbol table were
calculated wrongly from the phdrs because the main_bias wasn't taken into
account.

Formerly shared libraries did not get resolved properly:
	#2  0x00007fc4d86c56d6
	#3  0x0000000000400938 main

Fixed elfutils produce:
	#2  0x00007f61094876d6 libfunc
	#3  0x0000000000400938 main
