build: remove linking librt for backwards compatibility
Now that we require glibc 2.17+, #17538, we can remove linking in librt
for backwards compatibility purposes. The clock_* functions from librt
were merged into glibc as part of the 2.17 release.
* The `clock_*' suite of functions (declared in <time.h>) is now available
directly in the main C library. Previously it was necessary to link with
-lrt to use these functions. This change has the effect that a
single-threaded program that uses a function such as `clock_gettime' (and
is not linked with -lrt) will no longer implicitly load the pthreads
library at runtime and so will not suffer the overheads associated with
multi-thread support in other code such as the C++ runtime library.

Note that librt is already not linked by the RISC-V and AARCH64 binaries.
