[PR] Instrumentation: Add support for opening libs based on links /proc/self/map_files

Summary:
This commit adds support for opening libs based on links
/proc/self/map_files.  For this we're getting current virtual address
and searching the lib in the directory with such address range. After
that, we're getting full path to the binary by using readlink
function. Direct read from link in /proc/self/map_files entries is not
possible because of lack of permissions.
