Drop tcmalloc from SymEngine as it causes crashes with scipy

[Micket]

(created using eb --new-pr)
Use of tcmalloc causes some problems with SymEngine and SciPy-bundle

python3 -c "import symengine; import scipy.fft._pocketfft"

crashes. tcmalloc thinks it's a double free, so, either a bug in _pocketfft, or a but in tcmalloc I would guess. I can reproduce this with foss 2020b as well.

Since I don't know if there is a real bug in pocketfft, I propose to just drop gperftools from SymEngine instead.

(this particular bug is indirectly triggered by Qiskit 0.29 that i'm trying to add)

@boegelbot please test @ generoso

@Micket Why not add python -c "import symengine; import scipy.fft._pocketfft"
as a sanity check command?

[lexming]

I can confirm the bug and the fix.

LGTM

SciPy isn't actually a dependency here.

Ah, ok... Nevermind then. :)
