4ed8a59402 configure/bio_max_vecs: adapt to kernel 5.12 
The bio_alloc_bioset() function now BUG() if trying to allocate a bio
with more than BIO_MAX_VECS vectors.

A no-limit value (-1) is defined in order not to change old kernels'
behaviour.

ca3e1a5984 Revert "modules: use si_mem_available() when possible"

led to oom killer activation. This patch restores more conservative
free memory calculation method.

59d0492ef4 Specify modules source dir to avoid build warnings 
If we run 'make kernelversion' in a read-only dir then it produces

  mkdir: cannot create directory ‘.tmp_1056416’: Permission denied
  mkdir: cannot create directory ‘.tmp_1056420’: Permission denied
  mkdir: cannot create directory ‘.tmp_1056421’: Permission denied
  mkdir: cannot create directory ‘.tmp_1056423’: Permission denied

warnings. To avoid it we need to specify where the source (and build)
directory located.

Closes #540
