[toolchain/eglibc] AA: version 2.14 - rename patches folder to 2.14.1 (was 2.14)

The version string for eglibc 2.14 got changed from 2.14 to 2.14.1.
This string is also used to identify the patches-directory.
Since the patches-directory kept its name (2.14) none of the patches
got applied anymore.

[toolchain/eglibc] add patch for eglibc version 2.15

This patch partially reverts an (e)glibc commit
which fixed a memory leak, however introduced lookup
errors in dlopen() with resulting segmentation faults
in certain scenarios.
