Prevent exception when removing nonexistent file from a ramdisk fragment.

The previous implementation raised a FileNotFoundError if the file to
be removed did not exist in every extracted ramdisks.

This commit modifies this logic to attempt the file removal and only
raise the FileNotFoundError if the file was not successfully removed
from any of the ramdisk fragments.
