testsuite: add check for kmod_load_resources

Make sure we can call kmod_load_resources when we do have all the
mandatory indexes in place.

libkmod: fix return error when opening index

When calling kmod_load_resources() we could end up getting a bogus
return value -ENOMEM due to several other reasons, like the index not
existing. Change index_mm_open() to propagate the failure reason so we
can take actions on it or return to the caller.

libkmod: simplify lookup when builtin.modinfo.bin file is missing

When we try to lookup a module and builtin.modinfo.bin is missing, we
would do the right thing because the caller was replacing the return
code with 0 (and the list was not modified).

Make it simpler by allowing the caller to check and differentiate the
errors between module not found and index not found.

depmod: do not output .bin to stdout

index_write() relies on fseek/ftell to manage the position to which we
are write and thus needs the file stream to support it.

Right now when trying to write the index to stdout we fail with:

 depmod: tools/depmod.c:416: index_write: Assertion `initial_offset >= 0' failed.
 Aborted (core dumped)

We have no interest in outputting our index to stdout, so just skip it
like is done with other indexes.

While at it, add/remove some newlines to improve readability.

testsuite: check for ill-formed kcmdline

Commit ca3bf5d47cec ("iommu/amd: Introduces ivrs_acpihid kernel parameter")
in the kernel introduced an ill-formed kernel parameter, ivrs_acpihid.
The problem is that it may have a dot on the key side:
"ivrs_acpihid[00:14.5]=AMD0020:0". This could potentially trip our
parser of module options, but right now it's working as intended: the
only thing that happens is that after deciding "ivrs_acpihid[00:14" is a
module name, it will fail the underscores() routine and the option will
be ignored from the kmod pov (not kernel's pov since that driver parsers
the kernel command line by itself).

libkmod: ignore kcmdline option if we fail to parse modname

The error message is saying we are ignoring the option on the kernel
command line, so just do it.
