  Changed paths:

    M libc/test/src/stdlib/CMakeLists.txt
    M libc/test/src/stdlib/realpath_test.cpp

  Log Message:
  -----------
  [libc][realpath][test] Create test files/directories (#209369)

Follow-up PRs will add path validation etc to `realpath`, which will
require paths to exist in the filesystem.

This PR bumps the memory limit in `HermeticTestUtils.cpp`. The realpath
unit tests allocate quite a few strings, and since memory in hermetic
tests is never freed, the unit test quickly reaches the limit.
