scope docker doesn't work about appscope

the executable is dynamic. it presents as a Go exec as it includes several sections that identifies it as GO, including ".note.go.buildid".

when the library finds sections defining a Go exec it looks for the symbol "runtime.buildVersion". in this case, it finds the symbol and the address 0x0451a9c0. readelf confirms the symbol and address:
readelf -s /usr/bin/docker | grep buildVersion
106645: 000000000451a9c0 16 OBJECT GLOBAL DEFAULT 26 runtime.buildVersion
178064: 000000000451a9c0 16 OBJECT GLOBAL DEFAULT 26 runtime.buildVersion

the elf image defines that the symbol "runtime.buildVersion" is in the .data section and that the section is marked as LOAD.
from readelf (abbreviated):
LOAD 0x0000000002e74590 0x0000000002e75590 0x0000000002e75590
0x00000000017466b0 0x00000000017725b8 RW 0x1000
05 .init_array .fini_array .data.rel.ro .dynamic .got .data .go.buildinfo .noptrdata .bss .noptrbss

when the exec is loaded, addresses in the range defined for .data and .text are not mapped. therefore, a segfault results when referencing the defined address for "runtime.buildVersion".

taking the start load address as defined in the maps file and adding the value of the symbol defined for "runtime.buildVersion" results in an address that is in the mapped .data section.

so, we need to determine what is defining the load address and how to detect when we need to apply these values. will get back to this ASAP.
