[PATCH v2] include/common.h: fix build against recent 0.9.33 uClibc

[Baruch Siach]

An implementation of rpmatch() was backported to the 0.9.33 branch of uClibc.
So the uClibc version check introduced in commit 50c9e11f7e (include/common.h:
fix build against current uClibc) is not enough. Rename the local rpmatch()
implementation to avoid collision.
