Glob patterns seem unsupported for commands executed by the emulated
shell (LIT_USE_INTERNAL_SHELL=1). Disable the test while that is being
addressed (a workaround such as "cd a-*" also does not work).

Summary:
Error messages for dlsym used to be stored on the stack, but since
commit 2449ae7b ("ld.so: Introduce struct dl_exception") in glibc 2.27
these are now stored on the heap (and thus use the dlsym alloc pool).
Messages look like "undefined symbol: __isoc99_printf\0/path/to/a.out".
With many missing library functions and long object paths, the pool is
quickly exhausted. Implement a simple mechanism to return freed memory
to the pool (clear it in case it is used for calloc).
