libc: Default LIBC_INSTALL_PREFIX to ${CMAKE_INSTALL_PREFIX}
b22f448c21e718a3b6 added a rule to install libllvmlibc.a to
${LIBC_INSTALL_PREFIX}/${LIBC_INSTALL_LIBRARY_DIR}, which will be /lib
by default, which is disruptive to builds that stay within a user's
/home holder:
$ ninja install
...
-- Installing: /lib/libllvmlibc.a
CMake Error at projects/libc/lib/cmake_install.cmake:54 (file):
file INSTALL cannot copy file
"/home/nathan/cbl/github/tc-build/build/llvm/stage1/projects/libc/lib/libllvmlibc.a"
to "/lib/libllvmlibc.a": Permission denied.
Call Stack (most recent call first):

...
Change LIBC_INSTALL_PREFIX's default value to ${CMAKE_INSTALL_PREFIX} so
that 'ninja install' does not attempt to install anything outside of the
user's requested installation location.
