* Revert "Merge pull request #29909 from openedx/revert-29869-Carlos-Muniz/symmath-removal"
This reverts commit 8c0db8ddff, reversing
changes made to 1156c62014.
* fix: Remove misplaced `-e`
`-e` was wrongfully placed in front of `common/lib/sandbox-packages`,
which may have most likely been causing the edxAPP to break.
* fix: Change regex to apply to right dirs
`py38.txt` does not include `common/lib/xmodule` so it doesn't match the
regex. Therefore, it never got its lines in `common/lib/sandbox-packages`
fixed. If we change the regex to match any `common/lib/<packagename>` it
should work correctly.
scripts/post-pip-compile.sh uses common/lib/symmath/ as its sample
directory to clean up after using pip-tools. Since symmath has been
removed, xmodule, the largest of the directories in common/lib/ will
replace it.
