hurd: Do not make sigprocmask available in ld.so

After commit f7649d5780aa4682393b9daedd653e4d9c12784c ("dlopen: Do not
block signals"), the dynamic linker no longer uses sigprocmask, which
means that it does not have to be made available explicitly on hurd.

This reverts commit 892badc9bbcd4a6f8c2eb6c8a99be3aa22517532
("hurd: Make __sigprocmask GLIBC_PRIVATE") and commit
d5ed9ba29a3c818b3433a1784862494968abda45 ("hurd: Fix ld.so link"),
but keeps the comment changes from the second commit.
