Using `std::function` adds an extra layer of indirection, and in
particular, heap allocations that are not necessary in our use case
here.

Multiple sections may be marked as "r-xp" and with the executable's
path. We use the location of the `__nodetext` symbol added by the linker
script to ensure that the range we retrieve from the maps file does
indeed contain the Node.js text section.

During the addition of macOS support for large pages, a `memcpy` ended
up under the wrong preprocessor directive. As a result, the newly
allocated large pages were not initialized with a copy of the text
section.

Proposal to bring the support for this platform.
We assume the pse36 cpu flag is present for 2MB
large page support present in recent years
in mac line (not to be backported to 10.x anyway).
Recommended better for mac production servers rather
than casual mac books.

This commit also adds error handling. A THP-enabled build terminated
with an out-of-memory error on a system without /proc because it cast
the -1 from readlink() to size_t (i.e. ULONG_MAX) and then tried to
allocate a string of that size.
