pthread.h: manually align parameter lists

In previous patches, extern was mechanically removed from function
declarations without care to formatting, causing parameter lists to be
misaligned. Manually format changed sections such that the parameter
lists are realigned.

Viewing this patch with 'git diff -w' should produce no output.
