RFR: 8294772: Remove workaround in os::dll_address_to_library_name [v2]

[Johan Sjölen]

> I ported the BSD implementation of this function. According to the comment this bug should be fixed, as the oldest glibc I can see us supporting is 2.12.x. I've made an attempt at finding the bug that the comment refers to on glibc's bug tracker but has been unsuccesful in this.

> The second commit deletes what seems like an outdated comment (in os_bsd this refers to a code snippet right below the comment).
